🏢 Terminal Guide & Navigation
George Bush Intercontinental spreads across five terminals (A–E) arranged in a semi-circle with midfield gate piers. The airside Skyway runs above security and links all terminals; a landside Subway connects the same points on the baggage-claim level. Terminals A and B handle most domestic and regional operations, Terminal C houses United mainline, Terminal D concentrates international carriers, and Terminal E supports United long-haul and U.S. Customs and Border Protection processing. Clear signage at each checkpoint lists Skyway directions and elevator access.
Walking times inside a terminal are generally 5–10 minutes end to end (Terminal B’s north-south pier can reach 12–15 minutes). Skyway trains arrive every few minutes, with rides between adjacent terminals taking 2–3 minutes and full loops roughly 15 minutes; allow an extra 5 minutes for elevators if using mobility devices. Landside Subway trains are slightly slower but useful when re-clearing security.
Each terminal has its own TSA checkpoint; PreCheck is available in A (south), C (south), and E, and CLEAR kiosks operate in A and E. Morning bank peaks for United in C/E can create 20–30 minute waits, while late evenings usually remain under 15 minutes. International arrivals funnel through Terminal E’s CBP hall (with Global Entry, Mobile Passport, and APC kiosks) before a recheck belt for onward flights; passengers arriving into Terminal D walk or take the shuttle to the same facility.
Amenities include multiple United Clubs in B, C, and E plus the United Polaris Lounge near E12 for eligible long-haul passengers. Terminal D hosts the American Express Centurion Lounge near gate D6 and several airline lounges (KLM/Air France, British Airways). Dining highlights include local Houston brands like Pappadeaux, Hugo’s Cocina, and The Breakfast Klub across C and E, while Terminals A and B offer fast casual staples for regional travelers. Power outlets and bottle-fill stations sit near most Skyway landings.
Accessibility is supported by elevators at every train stop, moving walkways in C and E, and wheelchair assistance coordinated through airlines. Family amenities include nursing rooms near gates B12, C34, and E11, family restrooms spread across all concourses, and a small kids’ play area near Terminal B’s south pier—most with nearby seating to supervise.
Airlines Serving IAH
💡 Connection Tips
George Bush Intercontinental Airport (IAH) is a massive and bustling aviation hub in Houston, Texas, serving as a primary international gateway for the southern United States. For travelers, the most critical tip is understanding the terminal layout; IAH features five terminals (A, B, C, D, and E) connected by the 'Skyway' elevated train (airside) and the 'Subway' underground train (landside). If you are connecting between flights, use the Skyway to stay within the secure area and avoid re-clearing security; however, if you need to access baggage claim or the Marriott hotel, the Subway is the only option. Arriving at least 2 to 3 hours before international departures is standard to navigate the thorough security and customs processes. Ground transportation is well-developed; the airport is served by a variety of taxi fleets, ride-sharing services like Uber and Lyft, and the METRO bus network.
For those heading to downtown Houston, the METRO Bus 102 provides a budget-friendly link, while private shuttles and rental cars are the most flexible options for exploring the sprawling metropolitan area. Car rental agencies are located at a centralized off-site facility accessed via dedicated shuttle buses from the lower level of each terminal. A unique tip for travelers is the airport's 'Art Journey' program, featuring numerous large-scale installations across the terminals that are well worth exploring during a long layover. Facilities at IAH are world-class, offering a vast array of dining options including local Tex-Mex and international cuisine, extensive duty-free shops, and numerous airline lounges such as the United Club and the Centurion Lounge.
Complimentary high-speed Wi-Fi is available throughout the facility. The regional climate is humid subtropical, with the potential for localized morning fog and intense afternoon thunderstorms during the summer. When connecting to a long-haul international flight, always allow for a minimum 4-hour buffer to ensure a smooth transition through the larger hubs. IAH provide a professional and remarkably efficient arrival experience, reflecting the dynamic and global character of the Bayou City.
