Houston’s George Bush Intercontinental Airport (IAH) is one of the largest and busiest airports in the U.S., serving as a hub for United Airlines and welcoming millions of domestic and international travelers each year. For those seeking comfort, privacy, and amenities before their flight, IAH offers a range of airport lounges across all five terminals—A through E.
Whether you’re flying economy and hoping to use a credit card perk, or you’re a premium cabin traveler with elite airline status, here’s a complete guide to every airport lounge available at IAH.
Terminal A: Ideal for American Airlines Travelers
American Airlines Admirals Club
Located near Gate A25, the Admirals Club in Terminal A is a great option for American Airlines passengers. The lounge is open from early morning until early evening and provides a comfortable space to relax before your flight.
This lounge is accessible to Admirals Club members, American Airlines first and business class passengers, Oneworld elites, and certain credit cardholders. Day passes are also available for purchase or by redeeming miles.
Inside, guests can expect Wi-Fi, a buffet with snacks, premium beverages, televisions, and plenty of seating with power outlets. While it may not be the most luxurious lounge in the airport, it offers all the basics for a productive and restful layover.
Terminal B: Undergoing Major Renovation
United Club (Permanently Closed for Renovation)
Terminal B was once home to a United Club lounge, but it permanently closed in early 2025 to make way for a multi-year terminal redevelopment project. The new and improved lounge is expected to return by 2026 with enhanced amenities.
United Club Fly: A New Grab-and-Go Concept
To accommodate travelers during the construction, United has introduced a unique concept called United Club Fly in Terminal B. This grab-and-go lounge, which opened in 2025, provides a quick lounge experience with self-service food and drink options—minus the bar.
While you won’t find plush seating or alcohol here, the Fly lounge is ideal for short layovers, offering prepackaged meals, coffee, snacks, and beverages in a convenient self-check-in environment.
Terminal C: United Club and Private Suites
United Club (North and South Locations)
Terminal C features two United Club locations—one near Gate C1 and another near Gate C33. These lounges cater primarily to United passengers and Star Alliance members and are among the busiest at the airport.
Both lounges offer standard amenities like light snacks, Wi-Fi, complimentary beverages, business support, and customer service counters. Frequent flyers will find these lounges to be solid and reliable for both relaxation and work.
Minute Suites: Privacy by the Hour
Also located in Terminal C is Minute Suites, a unique pay-per-use lounge that offers private rooms 24/7. These suites include a daybed, smart TV, Alexa for voice controls, and workspace features. Priority Pass members can use one hour for free, with additional time billed by the hour.
Minute Suites is perfect for travelers looking for a nap, private calls, or a break from the terminal crowds. Showers are also available for a separate fee, making it one of the few places in the airport where you can freshen up mid-journey.
Terminal D: The Hub of Premium International Lounges
The Centurion Lounge by American Express
One of the most well-appointed lounges at IAH, the Centurion Lounge is located on the mezzanine level of Terminal D near Gate D12. Open from early morning to late evening, this lounge is available to AmEx Platinum, Centurion, and certain cardholders, with guest policies depending on the card tier.
Inside, you’ll find premium food curated by local chefs, a full-service bar, high-speed Wi-Fi, family rooms, dedicated work areas, and even showers. The Centurion Lounge is often ranked among the best airport lounges in the U.S. and is a top pick for eligible travelers.
KLM Crown Lounge
The KLM Crown Lounge is available to KLM business class passengers, Flying Blue elites, and SkyTeam Elite Plus members. It also admits Priority Pass holders, though entry can be limited based on capacity.
This lounge provides buffet-style dining, alcoholic and non-alcoholic drinks, espresso machines, and cozy seating areas. Though smaller than some other lounges, it offers great views and a peaceful ambiance.
Air France Lounge
Located across from Gate D18B, the Air France Lounge operates mostly in the afternoon and evening to accommodate its long-haul flights. It caters to Air France and SkyTeam passengers, but it also welcomes Priority Pass members during select hours.
The lounge provides a warm buffet, complimentary drinks, Wi-Fi, magazines, and a quiet place to rest before boarding.
HAS Executive Club Lounge
The HAS Executive Club Lounge serves a rotating group of premium passengers from airlines like British Airways, Emirates, and EVA Air. This lounge is not part of a major global alliance but offers exclusive access based on airline partnerships.
Inside, passengers can expect hot food, drinks, business amenities, and personalized service. It’s a good option for international travelers flying non-SkyTeam or non-Oneworld airlines.
USO Lounge: Support for Military Travelers
Located near Gate D8, the USO Lounge is a private facility open only to U.S. military personnel and their families. It provides free snacks, drinks, resting areas, children’s activities, and even computers for guest use.
This lounge is a welcome retreat for service members and offers a calm, supportive environment.
Terminal E: United Club for International Travelers
United Club (Terminal E Location)
The United Club in Terminal E serves many international flights and is one of the largest in the airport. It’s located on the upper level between Gates E11 and E12, offering a full bar, snacks, seating with charging ports, and travel agent support.
Though it doesn’t feature showers, this lounge is well-suited for long-haul travelers with international itineraries and provides easy access to Terminal D via the internal terminal train.
Tips for Navigating Lounges at IAH
Travelers at IAH benefit from a convenient airside train that connects all terminals without requiring re-entry through security. This means even if your flight departs from Terminal A, you can still visit the Centurion Lounge in Terminal D, or Minute Suites in Terminal C, without extra hassle.
However, lounge crowding—especially in Centurion and Priority Pass lounges—can be an issue during peak hours. It’s always smart to arrive early and have a backup plan.
Also, keep in mind that while most lounges provide snacks and drinks, only a few like the Centurion Lounge or HAS Executive Club offer hot meals and showers.
Conclusion
George Bush Intercontinental Airport (IAH) is well-equipped with a variety of lounges catering to different airline alliances, memberships, and needs. From the high-end amenities of the Centurion Lounge to the practical convenience of United Club Fly, the lounge offerings reflect Houston’s global travel importance.
As Terminal B continues to undergo a major facelift, lounge options across other terminals remain strong and diverse. Whether you’re flying for business, pleasure, or serving in the military, there’s a space at IAH to relax and recharge before your flight.
