IAH vs. HOU: Which Houston Airport Is Right for Your Trip?

You've booked a trip to Houston, or you're flying out of it, and your ticket options are split between two codes: IAH and HOU. They're not interchangeable. One sits 23 miles north of downtown and connects you to more than 185 nonstop destinations; the other sits about 11 miles southeast by road, runs mostly on Southwest, and gets you curbside faster. Picking the wrong one can add 40 minutes of driving, a terminal transfer you didn't plan for, or a fare that was higher than it needed to be. Here's how to choose with confidence.

Meet Houston's Two Airports: George Bush Intercontinental and William P. Hobby

George Bush Intercontinental (IAH) and William P. Hobby (HOU) are both run by the Houston Airport System, the City of Houston's aviation department, which also operates Ellington Airport and the Houston Spaceport. Together they form one of the largest public airport systems in North America, moving more than 63 million passengers in 2024.

Hobby is the older of the two. It opened in 1927 as a private airfield and served as Houston's primary commercial airport for decades, until Houston Intercontinental, later renamed for President George H.W. Bush, opened in 1969. Scheduled flights moved north to the new airport, and Hobby eventually resumed domestic service.

The character of each airport still reflects that history. IAH is Houston's international gateway and United Airlines' largest hub. Hobby is the compact, Southwest-dominated field close to town. Both have earned recognition for quality: Houston is the only city in the Western Hemisphere with two four-star-or-better Skytrax-rated airports, and Hobby remains North America's only 5-Star Skytrax airport, holding that rating for a fifth straight year in 2026.

Location and Drive Time: Which Airport Is Closer to You?

Hobby is closer to almost everything central. It sits roughly 11 miles southeast of downtown by road, while Bush Intercontinental is about 23 miles north. You'll feel that difference in the car and at the meter.

Ride-hailing bears this out. A trip from HOU to downtown typically runs $18 to $30 and takes 15 to 20 minutes. The same trip from IAH runs closer to $35 to $55 and 30 to 40 minutes, largely because of the extra distance and the North Freeway's habit of clotting up.

Where you're actually going matters more than the raw mileage:

• IAH is usually faster if you're heading to The Woodlands, north Houston suburbs, or the Galleria area.
• HOU is usually faster for the Texas Medical Center, NRG Stadium, Midtown, the Museum District, Sugar Land, and Pearland.

From most Houston addresses, Hobby lands within a 15-to-40-minute drive depending on traffic. If your hotel or office is on the south or southwest side, the choice is nearly made for you.

Airlines, Routes, and Destinations: Where Can Each Airport Take You?

IAH offers far broader reach. HOU offers depth on a handful of carriers. That single distinction resolves most of the debate.

What flies from IAH

Bush Intercontinental is United's largest US hub, with more than 200 destinations and roughly 185 nonstop routes across 27 airlines. Beyond United, you'll find Air France, Alaska, American, British Airways, Delta, and KLM, among others. International service to more than 70 destinations runs from Terminals D and E, while domestic flights operate mainly out of Terminals A, B, and C.

For overseas travel, IAH is effectively your only realistic option out of Houston. It's also the safer bet when frequency matters. United typically runs several daily flights on routes where Southwest offers only one nonstop into Hobby, which gives you options when a delay hits.

What flies from HOU

Hobby is a major Southwest operating base, and Southwest dominates its schedule. In total, HOU serves 56 domestic and 11 international destinations. Southwest launched international flights in October 2015 and now reaches Mexico, Central America, and South America from the West Concourse.

Other carriers operate from the Central Concourse's east side, including American, Delta, JetBlue, JSX, and Allegiant. Coverage on the legacy carriers is thin, though. Delta service at Hobby routes only through Atlanta, while IAH connects to all of Delta's major hubs. In practice, United owns IAH and Southwest owns HOU, and every other carrier works around that.

Terminal Experience, Amenities, and What to Expect on the Ground

Hobby feels smaller because it is smaller, and that shapes everything from your walk to your wait. It uses a single-terminal design with two concourses. IAH spreads across five terminals connected by an automated Skyway train.

Getting around inside

At Hobby, you're never more than about a 10-minute walk from your gate, and the longest possible trek, from the far end of the Central Concourse to the far end of the West Concourse, runs around 12 minutes along a corridor with moving walkways. The Central Concourse opened in 2003 with 25 gates (20-32 and 40-51); the West Concourse opened in October 2015 with five gates (1-5) for Southwest international and overflow domestic flights. You can read more about the layout and dining on the Central Concourse page.

IAH's five terminals demand more planning. Allow at least 15 minutes for a connection between terminals, and up to 25 at peak times. The Skyway keeps you inside security, but the distances are real.

Lounges, families, and extras

If pre-flight lounges matter, IAH wins outright. It has at least one lounge per terminal, including multiple United Clubs, an American Express Centurion Lounge, and an Admirals Club. Hobby's lounge options are limited to a USO Lounge (active military only, on the lower level near Gate 44) and a Gameway gaming lounge in the West Concourse near Gate 1.

Traveling with kids leans in Hobby's favor. Children's play areas sit near Gate 4 and Gate 40, with a wing slide, interactive smart screens, and a parachute structure. Both are open 24 hours. The linking corridor means you can reach concessions on either concourse without a marathon.

Parking, Getting There, and Planning Your Trip Around Houston

Both airports offer on-site garages and economy lots, but the ground-transport picture differs sharply, so it's worth planning before you drive. For a full rundown of terminals, dining, and getting around, the HOU airport guide is the place to start.

Getting to and from the airports

Hobby has a transit option IAH simply doesn't. A free HOU Connector bus links the airport to the Fannin South METRORail station, and METRO Bus 40 runs between Hobby, downtown, and the George R. Brown Convention Center from curb Zone 3 in about an hour. IAH has no rail connection at all. Your options there are car service, taxi, rideshare, or a limited bus.

Hobby also provides a complimentary Cell Phone Waiting Lot at 7600 Airport Boulevard, plus on-site EV charging: Blink stations in the Red Garage and ChargePoint stations in the Blue Garage.

Parking near Hobby

For self-parking with a shuttle, The Parking Spot runs two HOU locations on Airport Boulevard within 1.2 miles of the terminal, with rates starting around $6.50 a day, often 20 to 40 percent cheaper than airport parking. The Parking Spot 1 sits about 1.1 miles out and is easy to reach from I-45; The Parking Spot 2 is less than a mile west, convenient from the Sam Houston Tollway. Both include door-to-door shuttle service, luggage assistance, and a real-time shuttle tracker app. Prices change, so confirm current rates before you go.

IAH vs. HOU: A Quick-Reference Comparison for Every Type of Traveler

Here's how the two airports stack up side by side:

The right airport also depends on how you fly. Here's the choice by traveler type:

• International travelers: IAH, nearly always. It's Houston's only serious overseas gateway, with 70-plus international destinations and full-service carriers.
• Domestic travelers on Southwest: HOU. Fares are often lower, the layout is faster, and Southwest's schedule is deep.
• Domestic travelers needing maximum connections: IAH, through United's 200-plus destinations.
• Business travelers with global itineraries: IAH, for lounges, United hub connectivity, and complex routings.
• Business travelers on recurring domestic trips near downtown or the Medical Center: HOU, for faster processing and closer access.
• Families: HOU, for shorter walks, 24-hour play areas, and simpler navigation.

When the destination and price are a wash, it comes down to this: Hobby is closer and easier to get in and out of, while IAH is the more polished big-airport experience. A genuine coin toss if fares match.
