How Many Airports Are in Houston?
Houston, Texas, is served by two major commercial airports: George Bush Intercontinental Airport (IAH) and William P. Hobby Airport (HOU).
The Houston Airport System also operates Ellington Airport (EFD), which primarily handles general aviation, military, and aerospace activities rather than regular commercial passenger flights. When people ask about airports in Houston for airline travel, they almost always mean IAH and HOU.
How Many Major Airports Are in Houston, TX?
There are two major commercial airports in Houston: IAH and HOU.
What Is the Difference Between IAH and HOU Airports?
| Feature | IAH (George Bush Intercontinental) | HOU (William P. Hobby) |
|---|---|---|
| Size & Type | Large international hub | Medium-sized, more compact |
| Main Airline | United Airlines | Southwest Airlines |
| Location | 23 miles north of downtown | 7–11 miles southeast of downtown |
| Terminals | 5 terminals (A–E) | 1 main terminal + international |
| Focus | Domestic + extensive international | Mostly domestic + limited international |
| Passenger Volume | Significantly higher | Lower |
| Best For | International travel, United flights, northern suburbs | Southwest flights, downtown access, easier navigation |
IAH is the much larger airport and serves as a major United Airlines hub with extensive domestic and international routes. HOU is smaller, easier to navigate, and dominated by Southwest Airlines.
Which Airport Is Bigger, IAH or HOU?
IAH is significantly bigger than HOU in terms of physical size, number of terminals, passenger volume, and number of destinations.
Which Houston Airport Is Better to Fly Into?
It depends on your needs:
- Choose IAH for international flights, United Airlines, more airline options, or destinations in northern Houston/The Woodlands.
- Choose HOU for Southwest Airlines, quicker access to downtown, the Medical Center, or a simpler airport experience.
Which Airport Is Better, Hobby or IAH?
Neither is universally “better.” HOU (Hobby) is often preferred for convenience and shorter walks, while IAH offers far more flight options and international connectivity.
What Airport Is Cheaper to Fly Into in Houston?
There is no consistent winner. HOU often has competitive fares on Southwest and some low-cost carriers for domestic routes. IAH can be cheaper on certain routes due to more competition and United’s large network. Always compare both airports when booking.
How Far Apart Are IAH and HOU Airports?
The two airports are approximately 24 miles apart as the crow flies and about 30–35 miles by car, typically a 40–60 minute drive depending on traffic.
Can You Walk Between Terminals at Houston Airport?
At IAH, you cannot easily walk between all terminals. Terminals are connected by the free Skyway (above ground, inside security) and Subway (underground, outside security). Walking is possible between some terminals (especially B–E) inside security, but the trains are much faster and recommended.
At HOU, the airport is compact with essentially one main terminal area, so walking between gates is straightforward.
Is a 1-Hour Layover Enough Time in Houston?
A 1-hour layover can be tight, especially at IAH.
- At IAH, allow extra time if you need to change terminals or go through security/immigration.
- At HOU, a 1-hour connection is more realistic because the airport is smaller. Domestic-to-domestic connections on the same airline are more doable; international or inter-terminal changes require more buffer time.
Is Houston a Large Airport?
Yes. IAH is a large hub airport by U.S. and global standards, handling tens of millions of passengers annually. HOU is a medium-sized airport but still busy.
Which Airport Is Better, Houston or Dallas?
This depends on the comparison:
- Houston (IAH) vs Dallas-Fort Worth (DFW): Both are major hubs. DFW is generally larger and busier overall. IAH is a strong United hub; DFW is a major American Airlines hub.
- Houston (HOU) vs Dallas Love Field (DAL): Both are secondary airports dominated by Southwest and tend to be more convenient for domestic travel than their larger counterparts.
What Is the Current Wait Time for Security at Houston Airport?
Security wait times vary by terminal, time of day, and day of the week. At IAH, average waits are often in the 10–25 minute range during normal periods, but can stretch longer during peak morning and evening hours. HOU typically has shorter lines due to its smaller size. Check real-time TSA wait times on the official airport website or apps closer to your travel date, and consider TSA PreCheck or CLEAR for faster screening.
What Is the Least Used Airport in the US?
The least-used commercial airports in the U.S. are typically very small facilities in remote areas (often in Alaska or rural states) that handle only a few thousand passengers per year. Examples sometimes cited include tiny airports with minimal scheduled service. These change over time as airlines adjust routes.
Bottom line: Houston has two major commercial airports. Choose IAH for maximum flight options and international travel, or HOU for simplicity and Southwest Airlines. Always double-check your ticket for the correct airport code (IAH or HOU), as they are far enough apart that mixing them up can cause major problems.
