George Bush Intercontinental Airport is Houston’s main airport. It is about 23 miles from downtown Houston and serves over 62 million passengers a year. IAH is also the second largest hub for United Airlines, which means this airport has a strong lounge network and premium options for business travelers. There are 14 lounges in IAH including United Clubs, the American Airlines Admirals Club and the Centurion Lounge.
Many professional travelers do not consider travel time as a waste but they use it to answer their emails, prepare their presentation or make phone calls. Therefore, lounges at airports have become an important part of business travelers’ lives. A good lounge provides comfortable seating, WiFi, charging stations, food, drinks, quiet work areas and a break from crowded gate areas.
This IAH airport guide covers the best lounges at George Bush Intercontinental Airport, how to access them, what amenities they offer, and which lounges are perfect for business travelers.
IAH Terminal Layout
IAH has five terminals which are labeled as A, B, C, D and E. The Skyway train is used for moving between these terminals inside the secure area and the Subway train is used outside the security area. This movement between terminals matters because the best lounges may not always be in the terminal from where your flight leaves. So using these trains you can move between them and go to your most suited lounge.
One thing to know before you plan to visit is that the Terminal B lobby is closed on January 21, 2025, and will remain closed until late 2026. During this time passengers who are flying United Airlines from Terminal A, B, C or E must check in at the Terminal C lobby before departure gate. If you are flying through Terminal B plan extra time for this.
United Polaris Lounge
The United Polaris lounge is located in Terminal E near gate E12. It is not like the regular United Club but it is a step above them. You get dining, shower suites and daybeds for resting before a long flight. This is not for quick domestic flights but it is built for travelers who are about to sit on a plane for ten hours and want to eat a proper meal, take a shower and rest before boarding.
Access to this lounge requires a United Polaris business class ticket or travel in business class on a Star Alliance partner airline. If you can access this lounge then do not waste time in a regular lounge when this one is available.
United Club Lounges
United operates six lounges at IAH at Terminal A, B, C and E. Here is where to find them:
| Terminal | Location Notes |
| Terminal A | Multiple locations, serves domestic departures |
| Terminal B | South Mezzanine, above the United Express ticket counter |
| Terminal C | North and South concourses, two separate locations |
| Terminal E | Upper level, overlooks the atrium, tarmac views on one side |
Inside any United Club at IAH you get a complimentary bar, light snacks, free Wi Fi and comfortable seating. United Lounge at Terminal B also offers a conference room.
Access to these lounges is available to United Club members, Star Alliance Gold members, United 1K and Platinum members and cardholders of certain Chase United co-branded cards who receive complimentary one time passes each year.
The Centurion Lounge
The American Express Centurion Lounge at Houston’s George Bush Intercontinental Airport spreads over 8,500 square feet. It is open daily from 6 AM to 9:30 PM and located at Gate D12 in Terminal D.
Inside this lounge you get more than a typical lounge. There is a variety of seating including leather chairs, semi-private couches and benches. This lounge has a computer bar, a work area with charging options, a family room, high speed Wi-Fi, complimentary food all day, a premium bar and a reservable shower suite.
This lounge is accessible for travelers who carry an American Express Platinum or Centurion card.
Air France Lounge
This lounge is located in Terminal D’s departure area on level 2. It is accessible to Air France and SkyTeam business class passengers, Flying Blue elite members and Priority Pass members.
For business travelers who carry Priority Pass through their credit card, this lounge is the most useful option at IAH because it gives you access regardless of which airline you are flying that day. The food and drink setup is good and the atmosphere is calm and professional.
KLM Crown Lounge
The KLM Crown Lounge is located at Terminal D near gate D15 and is open daily from 6 AM to 9 PM.
Travelers with Business Class Standard or Flex tickets, Flying Blue Ultimate, Platinum or Gold membership or SkyTeam Elite Plus status can access all KLM lounges. To enter the lounge, you must be traveling on the same day with a KLM-operated flight, an international SkyTeam operated flight, or a domestic SkyTeam-operated flight that is connected to an international SkyTeam-operated flight.
American Airlines Admirals Club
This lounge is accessible for travelers with AAdvantage Executive Platinum, AAdvantage Platinum Pro or AAdvantage Platinum membership.
Admirals Club has standard amenities like drinks, snacks, WiFi and comfortable seating. It is a solid choice for American Airlines travelers who are passing through Houston.
Minute Suites
For business travelers who need to sleep, take a private call or just want to get rid of the noise for an hour, Minute Suites are the best option. You can book a private room by an hour or more. Inside that room you get a daybed, a desk and a TV.
Priority Pass members can bring up to 3 guests with them into the same suite. If you are traveling with a small team and want everyone in one space for a working session before flight this is useful.
USO Lounge
The USO Lounge is also located in Terminal D’s departure area. This lounge is for active duty military personnel, reservists, National Guard members and their families. It is free to use and offers a quiet space with useful amenities. If you or someone travelling with you qualifies, use it without hesitation.

Getting To and From IAH the Smart Way
IAH is about 23 miles from downtown Houston. This is a real distance and you need to plan for it because traffic on I 45 and the Beltway can add significant travel time. The airport itself is very busy so the roads around it also get congested due to passenger movement and parking activity.
Rideshare apps work fine during quiet hours, but during rush hours or late night arrivals, when driver availability is lower, rideshare becomes unpredictable. Prices surge, drivers may cancel at the last minute or arrive late. This is not ideal for business travelers who have a flight or an important meeting to attend after landing.
