Expedia Flights to and From Houston: 41 Popular Routes

Last updated: August 7, 2026. Airline routes, schedules, nonstop service, cabin availability, and fares can change; check current Expedia Flights for your travel dates.

Houston has one of the largest and most varied airport networks in the United States, which gives travelers far more choice than simply searching one airport. This guide highlights 41 popular Expedia Flights routes to and from Houston, covering major U.S. business centers, vacation destinations, airline hubs, Mexico and the Caribbean, Europe, Asia, the Middle East, South America, and Australia.

The city is primarily served by George Bush Intercontinental Airport (IAH) and William P. Hobby Airport (HOU). IAH is Houston’s larger airport and the city’s main long-haul international gateway, while Hobby can be especially useful for many domestic and short-haul leisure trips. Houston Airports reported 62.1 million passengers across its airports in 2025, including about 48 million at IAH and 14 million at HOU, and says the system connects Houston with more than 200 nonstop destinations in 2026.

Key Takeaways

• Main international airport: George Bush Intercontinental Airport (IAH).
• Major alternative: William P. Hobby Airport (HOU), particularly useful for many Southwest routes.
• Strong domestic choices: Houston has nonstop links with major markets including Dallas, Atlanta, Denver, Chicago, Los Angeles, New York, Orlando, Miami, Seattle, Boston, and San Francisco.
• International strength: IAH offers an unusually broad collection of nonstop routes to Mexico, Europe, Asia, the Middle East, South America, and Australia.
• Good vacation choices: Cancún, Orlando, Las Vegas, Miami/Fort Lauderdale, and Los Angeles can often be compared from more than one Houston airport.
• Good to know: The 41 routes below are numbered for easy browsing rather than presented as a strict popularity ranking.

Popular U.S. Expedia Flights from George Bush Intercontinental Airport

1. Houston IAH ↔ Dallas/Fort Worth DFW

Dallas/Fort Worth is one of the easiest short-haul trips to compare from Houston. The IAH–DFW airport pair is served nonstop by both American Airlines and United, giving travelers meaningful schedule and airline choice on a flight that is only about an hour and a half in the air. It can work particularly well for business trips, family visits, and travelers connecting onward through American’s large DFW network.

If you are simply traveling between Houston and Dallas, compare DFW with the Hobby-to-Dallas Love Field option later in this guide. DFW is much larger and particularly useful for connections, while Love Field may make more sense for some Dallas destinations. Compare IAH to DFW flights on Expedia, or use Expedia’s Houston flight search for the inbound trip.

2. Houston IAH ↔ Atlanta ATL

Atlanta is useful both as a destination and as one of the country’s most important connecting gateways. Current nonstop service from IAH includes Delta, United, and Frontier, giving travelers several ways to compare the roughly two-hour trip. That mix can be useful when departure time matters just as much as price.

Travelers connecting through Atlanta may find Delta particularly relevant because ATL is its largest hub, while United can be convenient for travelers already building a trip around the carrier’s Houston network. If Atlanta itself is your destination, compare total trip time and fare conditions rather than assuming the lowest displayed base fare will be the best fit after bags and seat choices are considered. View Houston–Atlanta flights on Expedia.

3. Houston IAH ↔ Denver DEN

Denver is a strong route for both Colorado trips and connections farther west. United and Frontier currently operate nonstop service from IAH, with a typical nonstop flight taking roughly two and a half hours. The route can be especially useful for ski trips, mountain vacations, business travel, and itineraries that connect through Denver to smaller western cities.

Houston travelers also have a Hobby–Denver option, so checking both airports is worthwhile if you have flexibility. IAH may suit travelers living north of central Houston or connecting on United; HOU may be attractive for Southwest travelers or anyone who finds Hobby more convenient. Compare IAH–Denver flight options.

4. Houston IAH ↔ Chicago O’Hare ORD

O’Hare is one of Houston’s most useful northern business and connection routes. American, United, and Frontier currently appear as nonstop operators from IAH, and the flight generally runs under three hours. For travelers continuing elsewhere, both United and American maintain major operations at ORD, which can make the airport useful far beyond Chicago itself.

Houston also has nonstop service from Hobby to Chicago Midway, creating a genuine airport-choice decision. O’Hare can be preferable for international connections and many suburban destinations; Midway may be convenient for Southwest travelers and some parts of Chicago. Search IAH to Chicago O’Hare on Expedia.

5. Houston IAH ↔ Los Angeles LAX

Los Angeles is one of the strongest examples of why Houston travelers should compare more than one airline and more than one departure airport. From IAH, current nonstop operators include United, American, Delta, and Frontier. That level of competition gives travelers a useful mix of schedules and fare types on a flight of roughly four hours.

LAX works for vacations, entertainment-industry travel, business trips, and onward connections across the Pacific. Hobby also has nonstop Los Angeles service, so the airport closest to you can make a substantial difference to the overall journey. Compare IAH–LAX flights on Expedia.

6. Houston IAH ↔ Newark EWR

Newark is a particularly important Houston route for travelers headed to the New York metropolitan area or connecting through United’s Newark hub. United currently operates the nonstop service from IAH, and the trip takes roughly three and a half hours in normal scheduling.

EWR can be a good choice for Lower Manhattan, parts of New Jersey, and many onward United connections, but it is not automatically the best New York airport for every traveler. LaGuardia and JFK serve different needs, so compare where you are actually staying before choosing purely by fare. View Houston to Newark flights.

7. Houston IAH ↔ New York LaGuardia LGA

LaGuardia can be one of the most practical choices for a trip focused on Manhattan, Queens, or a short New York business visit. Current nonstop service from IAH includes United and Delta, giving travelers more than one major carrier to compare.

For Houston travelers, the biggest question is often not whether to fly to New York but which New York airport to choose. LGA can be convenient for many city trips, while Newark may work better for New Jersey or United connections and JFK may be more useful for certain international itineraries. Compare total ground travel as well as airfare. Check IAH–LGA flights on Expedia.

8. Houston IAH ↔ Orlando MCO

For family vacations and theme-park trips, Orlando is one of Houston’s easiest leisure routes to compare. United and Frontier currently operate nonstop IAH–MCO service, with a typical flight of around two and a half hours.

Families should also compare Hobby because Southwest serves Orlando nonstop from HOU. The ability to choose between two Houston airports can be valuable when several people are traveling together, especially once luggage, seat selection, airport transportation, and departure times are considered. Compare IAH to Orlando flights.

9. Houston IAH ↔ Miami MIA

Miami is an important route for South Florida vacations, cruise departures, business trips, and connections into Latin America and the Caribbean. American, United, and Frontier currently operate nonstop between IAH and MIA, giving travelers useful competition on a flight of roughly two and a half hours.

If your actual destination is north of Miami, compare Fort Lauderdale as well. Hobby has nonstop HOU–FLL service, which can change both your Houston-side and South Florida ground transportation. Search current IAH–Miami flights.

10. Houston IAH ↔ Las Vegas LAS

Las Vegas is a straightforward nonstop leisure option from IAH, currently served by United and Frontier. The nonstop trip is a little over three hours, making it realistic for long weekends as well as longer Nevada or Southwest road trips.

Hobby also has nonstop Las Vegas service. That makes this a route where checking both Houston airports can be especially worthwhile. Rather than comparing only the headline fare, consider how early you need to leave home, checked-bag costs, and which airport is easier for your group. View IAH–Las Vegas flights on Expedia.

11. Houston IAH ↔ Phoenix PHX

Phoenix is useful for Arizona vacations, business travel, golf trips, spring training, and connections across the Southwest. American, United, and Frontier currently offer nonstop IAH–PHX service, with the nonstop trip generally just under three hours.

American’s Phoenix presence can make the route useful for onward connections, while United is an obvious option for travelers already using its IAH hub. When Phoenix is the final destination, simply compare the nonstop schedule that works best for your day. Compare Houston–Phoenix flights.

12. Houston IAH ↔ Boston BOS

Boston is a strong nonstop option for New England business trips, university visits, fall vacations, and trips continuing elsewhere in the region. United and JetBlue currently operate nonstop service from IAH, creating useful carrier choice on a route of roughly four hours.

Because Boston Logan is close to the city compared with many large U.S. airports, the nonstop can be particularly attractive for a short urban trip. If you have specific baggage, seat, or flexibility needs, compare fare conditions carefully before choosing between carriers. View IAH–Boston flight options.

13. Houston IAH ↔ San Francisco SFO

San Francisco is one of Houston’s important West Coast business and technology routes. United currently operates the nonstop IAH–SFO service, and the flight is generally a little over four hours.

SFO is also a major international gateway, so this route can be useful for passengers continuing to destinations across the Pacific. If Northern California itself is your destination, compare SFO with other Bay Area airports if your plans are centered outside San Francisco proper. Search IAH–SFO flights on Expedia.

14. Houston IAH ↔ Seattle SEA

Seattle is an appealing nonstop for Pacific Northwest vacations, Alaska cruise itineraries, technology-sector business travel, and connections onward. Alaska Airlines and United currently serve IAH–SEA nonstop, giving travelers two distinct network options.

The flight is roughly four and three-quarter hours, making departure timing worth considering. A convenient nonstop can save significant time compared with an itinerary that changes planes in Denver, Dallas, or another western hub. Compare Houston–Seattle flights on Expedia.

15. Houston IAH ↔ Washington National DCA

For a trip centered on Washington, D.C., Reagan National is attractive because of its close-in location. United and American currently operate nonstop service between IAH and DCA, with a typical flight of about three hours.

The route is especially useful for government, corporate, conference, and short city trips where minimizing ground travel at the destination matters. Washington Dulles is another option from IAH and can be preferable for some suburbs or international connections, so airport geography deserves a quick look before booking. View IAH–DCA flights.

16. Houston IAH ↔ Charlotte CLT

Charlotte is an important southeastern business market and a major American Airlines connecting hub. American, United, and Frontier currently operate nonstop flights from IAH, with the trip usually taking around two and a half hours.

The route is useful both for Charlotte itself and for onward trips throughout the Carolinas and Southeast. If you are connecting, compare total itinerary duration rather than focusing only on the first segment; a slightly more expensive itinerary can sometimes produce a much easier connection. Compare IAH–Charlotte flights.

17. Houston IAH ↔ San Diego SAN

San Diego is a particularly appealing nonstop for Southern California vacations, conventions, military-related travel, and trips to the region’s beaches and family attractions. United currently operates nonstop service between IAH and SAN, with a flight time of roughly three and a half hours.

For travelers whose final destination is San Diego County, flying directly into SAN can be much easier than landing at LAX and driving south. The trade-off is that Los Angeles generally has more airline competition, so compare both only when the extra ground journey from LAX genuinely makes sense. View current Houston–San Diego flights.

Mexico and Caribbean Flights from Houston IAH

18. Houston IAH ↔ Cancún CUN

Cancún is one of Houston’s standout international vacation routes. United and Frontier currently operate nonstop service from IAH, and Houston Airports identified Cancún among United’s most-booked Houston destinations for summer 2026. The nonstop flight is only around two and a half hours, putting the Mexican Caribbean within surprisingly easy reach.

Hobby also has nonstop Cancún service, so this is another route where Houston residents should compare airports rather than automatically choosing IAH. Families and resort travelers should compare checked-bag allowances, seat costs, departure times, and the total airport journey. Compare IAH–Cancún flights.

19. Houston IAH ↔ Mexico City MEX

Mexico City is one of the deepest airline-choice routes in Houston’s international network. Current nonstop operators include Aeromexico, United, Viva, and Volaris. With a flight of roughly two and a half hours, it works for business travel, family visits, weekend trips, and onward connections within Mexico.

The variety of carriers means it is particularly important to compare what each fare includes. A low base fare may handle baggage, advance seat choice, flexibility, and cabin options differently from another ticket on the same airport pair. Search current IAH–Mexico City flights.

European Expedia Flights from Houston

20. Houston IAH ↔ London Heathrow LHR

London Heathrow is one of Houston’s most useful transatlantic routes. British Airways and United currently operate nonstop flights between IAH and LHR, providing both airline choice and strong onward connectivity. The nonstop journey is approximately nine hours eastbound in scheduled duration, though actual flight time varies.

For travelers continuing into Europe, Heathrow offers a large onward network, but connecting there is not always the simplest option. Compare the full itinerary against Houston’s nonstops to Amsterdam, Frankfurt, Paris, Rome, and other European gateways. If London is your destination, the nonstop is difficult to beat for convenience. Compare Houston–London flights on Expedia.

21. Houston IAH ↔ Paris Charles de Gaulle CDG

Paris is a valuable nonstop choice for travelers heading directly to France or connecting through Air France’s Charles de Gaulle network. Air France currently operates the nonstop IAH–CDG route, with a scheduled nonstop duration of roughly nine hours and twenty minutes.

The route can be especially attractive for travelers whose European plans begin in France, Belgium, or destinations that connect efficiently through CDG. For multi-country trips, compare Paris with Amsterdam, Frankfurt, and London before deciding which gateway produces the simplest overall itinerary. View Houston–Paris flights.

22. Houston IAH ↔ Amsterdam AMS

Amsterdam Schiphol is another excellent European gateway from Houston. KLM and United currently operate nonstop IAH–AMS service, creating a useful choice between two major international networks. The nonstop is approximately nine hours and twenty minutes in published schedules.

Amsterdam can work particularly well for the Netherlands itself and for connections around Europe. When comparing connecting trips, look beyond the first fare and consider total journey time, connection length, baggage handling, and whether every segment is on the same ticket. Compare IAH–Amsterdam flights.

23. Houston IAH ↔ Frankfurt FRA

Frankfurt is a major business and connecting route between Houston and continental Europe. Lufthansa and United currently operate nonstop service, with a published flight time around nine hours and forty minutes.

The airport’s large connecting network makes Frankfurt especially useful for Germany, Central Europe, and destinations farther east. Travelers who dislike large connecting hubs may still prefer a nonstop to the European city closest to their final destination, so compare the full trip rather than choosing FRA simply because it offers many connections. View IAH–Frankfurt flights.

24. Houston IAH ↔ Rome Fiumicino FCO

Rome is one of the most notable additions to Houston’s 2026 international network. ITA Airways launched the first nonstop IAH–Rome service on May 1, 2026. During the main summer schedule, service operates up to five times weekly, with the published 2026 seasonal schedule running through October 24.

For travelers planning Italy, the nonstop removes the need to begin the trip with a connection elsewhere in the U.S. or Europe. Because this service is seasonal rather than something to assume is available every day of the year, check your exact dates before building the rest of the trip around it. Compare Houston–Rome flights.

Asia-Pacific Flights from Houston

25. Houston IAH ↔ Tokyo Narita NRT

Tokyo Narita gives Houston travelers a nonstop route to Japan with current service from United and ZIPAIR. This makes NRT particularly interesting because travelers can compare a traditional global-network airline with a different long-haul fare model.

The journey is roughly fourteen hours, so fare details and comfort choices matter more than they might on a short domestic flight. Compare baggage, seat selection, meals, change conditions, and cabin options carefully rather than assuming similarly priced tickets include similar products. Houston also has nonstop service to Tokyo Haneda, so check which Tokyo airport better fits your plans. View IAH–Narita flights.

26. Houston IAH ↔ Tokyo Haneda HND

Haneda is particularly appealing when Tokyo itself is your destination because it is generally more convenient for central Tokyo than Narita. ANA currently operates the nonstop IAH–HND route, giving Houston a second nonstop Tokyo airport choice.

For a trip ending in Tokyo, the added ground-transport convenience of Haneda may outweigh a modest airfare difference. For a connection beyond Tokyo, however, the best airport can depend on the onward airline and schedule. Compare HND and NRT before committing to one. Search Houston–Haneda flights on Expedia.

27. Houston IAH ↔ Taipei TPE

Taipei is an important nonstop link between Houston and East Asia. EVA Air currently operates IAH–TPE nonstop service, with the journey running around sixteen hours or more depending on direction and conditions.

The route is valuable not only for Taiwan but also for travelers using Taipei as an onward gateway in Asia. On a flight this long, compare cabin class, fare restrictions, baggage, seat choice, and connection time more carefully than you might on a domestic trip. Compare IAH–Taipei flights.

28. Houston IAH ↔ Sydney SYD

Sydney is one of the most remarkable routes in Houston’s network simply because of the distance it covers without a connection. United currently operates nonstop service between IAH and SYD, with scheduled flying time of roughly seventeen and a half hours.

For Australia-bound travelers, avoiding a connection in Los Angeles or San Francisco can make the itinerary considerably simpler even though the individual flight is exceptionally long. Pay particular attention to seat comfort, cabin options, arrival timing, and the conditions attached to your fare. View Houston–Sydney flights on Expedia.

Middle East Flights from Houston

29. Houston IAH ↔ Dubai DXB

Dubai gives Houston a nonstop connection to one of the world’s largest long-haul connecting hubs. Emirates currently operates IAH–DXB nonstop service, with scheduled flight time approaching fifteen hours.

The route can make sense for Dubai itself or for onward trips across the Middle East, South Asia, Africa, and parts of Asia. When connecting, compare the complete journey against alternatives through Doha, Istanbul, Europe, or an Asian gateway rather than assuming one hub will always be fastest. Compare Houston–Dubai flights.

30. Houston IAH ↔ Doha DOH

Doha is another major one-stop gateway from Houston to destinations well beyond Qatar. Qatar Airways currently operates nonstop IAH–DOH service, with the flight taking roughly fourteen and a half hours.

For travelers continuing to South Asia, Southeast Asia, Africa, or the Middle East, the real comparison is often the total connecting itinerary rather than Houston–Doha alone. Look closely at layover time and the operating airline on each segment. View IAH–Doha flight options.

31. Houston IAH ↔ Istanbul IST

Istanbul combines a compelling destination with extensive onward connectivity. Turkish Airlines currently operates the nonstop IAH–IST route, with published flying time around twelve hours.

The route can be particularly useful for travelers continuing into southeastern Europe, Central Asia, the Middle East, or Africa. Because an international itinerary may contain several fare and baggage rules across different segments, inspect the complete ticket before purchasing. Compare Houston–Istanbul flights.

South America Flights from Houston

32. Houston IAH ↔ São Paulo GRU

São Paulo is one of Houston’s most important South American business links. United currently operates nonstop IAH–GRU service, with a scheduled journey of roughly ten hours.

The route is particularly useful for the energy, corporate, and industrial traffic that connects Texas and Brazil, but it is equally valuable for travelers beginning a broader South American trip. If your final destination lies elsewhere in Brazil, compare onward domestic connections at GRU with one-stop alternatives through other gateways. View Houston–São Paulo flights.

33. Houston IAH ↔ Bogotá BOG

Bogotá gives Houston travelers a nonstop option into Colombia and a useful gateway for travel around northern South America. United currently operates nonstop IAH–BOG service, with the trip taking just under five hours.

Houston’s Colombia network is also expanding: United has announced Cartagena service beginning later in 2026, supplementing existing Bogotá and Medellín links. For travel now, Bogotá remains one of the most practical year-round Colombian gateways from Houston. Compare IAH–Bogotá flights on Expedia.

Popular Expedia Flights from William P. Hobby Airport

Hobby is much smaller than IAH, but that can be part of its appeal. It offers a broad Southwest network plus service from several other airlines, and Houston Airports lists dozens of domestic and international nonstop destinations from HOU. For travelers staying south or southeast of central Houston, Hobby may also reduce the ground journey compared with IAH.

34. Houston HOU ↔ Dallas Love Field DAL

Hobby to Dallas Love Field is one of the classic short-haul Texas routes and a useful alternative to flying IAH–DFW. Southwest serves HOU–DAL nonstop, making it particularly relevant to travelers whose destination is central Dallas or who simply prefer Hobby on the Houston side.

The real choice here is often airport-to-airport convenience rather than flight time. DFW offers a huge connection network, while Love Field can be more convenient for many Dallas trips. Compare Hobby–Dallas Love Field flights.

35. Houston HOU ↔ Chicago Midway MDW

Chicago Midway gives Houston travelers a useful alternative to O’Hare. Southwest currently serves HOU–MDW nonstop, and Midway can work well for travelers headed to downtown Chicago or neighborhoods where its location is more convenient.

Compare this route with IAH–ORD rather than assuming one airport pair is always better. O’Hare offers more airline and international connection possibilities; Hobby–Midway can be simpler for a point-to-point Southwest itinerary. View HOU–Chicago Midway flights.

36. Houston HOU ↔ Baltimore/Washington BWI

BWI is a useful Hobby nonstop for Baltimore, parts of Maryland, and travelers who can conveniently reach Washington from the north. Southwest serves the route nonstop, providing an alternative to the IAH–DCA and IAH–Dulles choices.

If Washington, D.C. is your actual destination, compare ground transportation carefully. DCA is much closer to central Washington, while BWI may make more sense for Baltimore or northern parts of the region. Compare HOU–BWI flights.

37. Houston HOU ↔ Orlando MCO

Hobby–Orlando is one of Houston’s most family-friendly nonstop choices. Southwest operates nonstop service from HOU, giving travelers another option beyond IAH–MCO.

For a family of four or five, airport choice can materially affect the trip. Compare fares after adding the bags and seat choices you actually need, then consider parking or rideshare costs and the departure time. A slightly higher airfare from the closer Houston airport can sometimes produce the easier overall trip. View Hobby–Orlando flights.

38. Houston HOU ↔ Las Vegas LAS

Southwest’s nonstop Hobby–Las Vegas service is an attractive option for long weekends, conventions, sports trips, and Nevada vacations. Because IAH also has nonstop Las Vegas flights, Houston travelers can compare departure airport as well as airline.

If Hobby is substantially closer to home, a modest fare difference may be less important than the time saved before and after the flight. Conversely, travelers connecting through IAH may find the Intercontinental option easier. Compare Hobby–Las Vegas flights.

39. Houston HOU ↔ Los Angeles LAX

Hobby–LAX gives Southwest travelers a nonstop option between Houston and Los Angeles without using IAH. It can be especially convenient for travelers based closer to Hobby who want a point-to-point trip to Southern California.

IAH–LAX has considerably more nonstop-airline competition, so comparing both airport pairs is worthwhile. The best choice may differ from one trip to the next depending on schedule and fare. View HOU–Los Angeles flights.

40. Houston HOU ↔ Fort Lauderdale FLL

Fort Lauderdale is a handy nonstop choice for South Florida beaches, cruises, and trips focused north of central Miami. Southwest currently serves HOU–FLL nonstop.

Compare this with IAH–Miami if your destination could reasonably be reached from either airport. Fort Lauderdale can be more convenient for Broward County and some cruise plans, while Miami International is better positioned for other parts of the region and offers a different airline mix. Compare Hobby–Fort Lauderdale flights.

41. Houston HOU ↔ Cancún CUN

Cancún is one of Hobby’s most useful international leisure routes. Southwest serves HOU–CUN nonstop, creating a second Houston-airport choice alongside nonstop IAH–Cancún service.

That airport competition is particularly useful for resort trips because travelers can compare not only airfare but also departure time and the practical cost of reaching each Houston airport. If you live south of downtown, Hobby may be substantially easier; if you live north of Houston, IAH may be the natural choice. View Hobby–Cancún flights on Expedia.

IAH or Hobby: Which Houston Airport Should You Choose?

There is no single answer for every traveler. IAH is usually the first airport to check for long-haul international travel, United connections, and destinations that Hobby does not serve nonstop. Its current airline roster includes carriers from North America, Europe, the Middle East, Asia, and Latin America.

Hobby is worth checking for many domestic and shorter international trips, particularly where Southwest operates nonstop service. Houston Airports currently lists destinations including Dallas Love Field, Chicago Midway, Orlando, Las Vegas, Los Angeles, Fort Lauderdale, Cancún, San José, Liberia, Belize City, Puerto Vallarta, and Los Cabos among Hobby’s network.

Before You Book Houston Flights

Check whether your flight is really nonstop

A list of airlines shown on a flight-search page can include connecting itineraries as well as nonstop service. If avoiding a connection matters, use the nonstop filter and inspect the actual itinerary before purchasing.

Compare what the fare includes

Two economy tickets on the same route can come with very different rules. Check baggage, advance seat choice, change conditions, cancellation conditions, boarding benefits, and whether the fare is a restrictive basic product or a more flexible option.

Do not assume every premium option is the same

Domestic first class, international business class, premium economy, and extra-legroom economy are different products. On connecting itineraries, the premium cabin displayed for the trip may not necessarily apply to every segment.

Recheck seasonal routes

Houston has seasonal routes at both airports. A flight available in summer may not operate on winter dates, and frequency can change during the year. Rome is a good current example: ITA Airways’ announced 2026 Houston schedule is seasonal through October 24.

Check your terminal before heading to IAH

IAH has been completing major international-terminal changes. In 2026, international check-in arrangements for several foreign carriers moved as Terminal E became fully operational, so confirm your current terminal and check-in location with your airline before leaving for the airport.

Frequently Asked Questions About Expedia Flights to and From Houston

What are the main airports for flights to Houston?

The two principal scheduled passenger airports are George Bush Intercontinental Airport (IAH) and William P. Hobby Airport (HOU). IAH is Houston’s primary international gateway and much larger connecting airport. Hobby handles an extensive domestic and short-haul international network, with Southwest particularly prominent there.

Is IAH or HOU closer to Downtown Houston?

Hobby is substantially closer to central Houston in general geographic terms. Houston Airports currently places HOU approximately 11 miles southeast of downtown and IAH approximately 22 miles north. Actual driving time varies with traffic and your exact destination.

Which Houston airport has more international flights?

IAH. It is Houston’s primary long-haul international airport and has nonstop service across Europe, Asia, the Middle East, Latin America, Canada, the Caribbean, and Oceania. Hobby has international service too, but on a much smaller scale.

Can I fly nonstop from Houston to Europe?

Yes. Current IAH routes covered in this guide include London Heathrow, Paris Charles de Gaulle, Amsterdam, Frankfurt, and Rome. Other European routes may also be available depending on the schedule period. Houston’s Rome route is seasonal in its published 2026 schedule.

Can I fly nonstop from Houston to Asia?

Yes. Current nonstop examples include Tokyo Narita, Tokyo Haneda, and Taipei. IAH’s airline list also includes several major Asian carriers, reflecting Houston’s broad long-haul network.

Can I fly nonstop from Houston to Australia?

Yes. United currently operates nonstop service between IAH and Sydney. Because it is an ultra-long-haul flight, carefully compare cabin, seat, baggage, and fare conditions for your dates.

Which Houston routes give me a choice between IAH and HOU?

Several major markets can be reached nonstop from both airports, including Orlando, Las Vegas, Los Angeles, and Cancún. The exact airline mix differs by airport. Houston travelers can also compare nearby-airport pairs such as IAH–DFW versus HOU–DAL and IAH–ORD versus HOU–MDW.

Are baggage fees included when I search Expedia Flights?

Baggage inclusion depends on the airline, route, and fare you select. Do not assume every economy fare includes the same carry-on or checked-bag allowance. Review the exact fare details and the operating airline’s current baggage rules before purchasing.

Can I choose seats when booking a flight through Expedia?

Seat-selection availability depends on the airline and fare. Some tickets may include advance seat selection, while others may charge for it or restrict which seats can be chosen. Connecting itineraries can also involve different rules on different segments.

Can Expedia flight tickets be changed or cancelled?

That depends on the ticket. Refundability, voluntary changes, airline credits, and cancellation conditions vary by airline, route, and fare type. Read the exact ticket rules shown for your itinerary rather than assuming a general policy applies to every flight.

What should I compare besides airfare?

For Houston, start with the departure airport. Then compare nonstop versus connecting service, departure time, total travel time, baggage, seat selection, cabin, fare flexibility, and arrival airport. On international trips, the length and quality of any connection can matter as much as the headline fare.

Finding the Right Houston Flight for Your Trip

Houston’s biggest advantage is choice. IAH provides a huge domestic network and unusually strong nonstop international coverage, while Hobby adds another substantial collection of routes that can be more convenient for many travelers. That means the smartest Expedia Flights search often begins by checking both Houston airports whenever your destination is served from each.

For short trips, airport location and flight timing may matter most. For family vacations, baggage and seat arrangements can quickly change the real trip cost. For long-haul travel, cabin comfort, connection quality, and fare flexibility become more important. And when you have a nonstop option, it is worth comparing the time saved against any price difference before choosing a connecting itinerary.

Routes and schedules continue to evolve. Houston added nonstop Rome service in 2026, Caracas service is scheduled to resume shortly after this guide’s publication date, and Cartagena is scheduled to join the network later in the year. That makes checking the current schedule for your actual dates especially worthwhile.
