George Bush Intercontinental Airport (IAH)

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.
