Overview of IAH
George Bush Intercontinental Airport serves as Houston’s primary airport and a critical gateway for travelers in the southern United States. The facility connects to over 180 destinations worldwide, making it a vital hub for United Airlines and other major carriers. The airport’s five terminals are interconnected by the Skyway (an above-ground train within the secure area) and a subway train (outside the secure area), facilitating efficient movement for passengers. A central Marriott hotel, located outside the secure area, adds convenience for layovers or overnight stays.
The airport’s infrastructure includes multiple runways, extensive parking facilities, and a range of services catering to diverse traveler needs. Accessibility is enhanced through roadway systems looping all terminals and parking areas, with entry points from the east and south. IAH’s design emphasizes functionality and passenger comfort, offering Southern hospitality alongside modern amenities like dining, shopping, and lounges.
Terminal Breakdown
IAH’s five terminals—A, B, C, D, and E—cater to specific airlines and flight types, with distinct layouts and amenities. Terminals A, B, and C primarily serve domestic flights, while Terminals D and E handle both domestic and international operations. Terminal A operates independently, requiring train transport to connect to other terminals, whereas Terminals B, C, D, and E are linked via airside walkways within the secure area.
Terminal A
Departures
Terminal A features two concourses: the north concourse with 18 gates (A1, A2, A3A–A3H) and the south concourse with 11 gates (A17–A20, A24–A30). Security checkpoints at both ends lead to the departure areas. The north concourse houses a United Club, while the south concourse offers an Admirals Club for eligible passengers. Travelers can access the Skyway train on level 3 for connections to other terminals within the secure area or use the subway on level LL (lower level) if exiting the secure area.
Arrivals
Level 1 of Terminal A contains the arrivals area, including baggage claim and access to ground transportation and parking. The layout ensures quick access to taxis, ride-shares, and shuttles located outside the terminal.
Terminal B
Departures
Terminal B, primarily used by United Airlines, features a single security checkpoint accessing north and south concourses. The south concourse serves 30 gates (B1–B12, B14–B31), while the north concourse has 9 gates (B76/A, B77/A, B79/A, B80, B81/A, B83/A, B85A/B, B87, B88). A United Club is located in the south mezzanine, above the United Express ticket desk. Passengers can walk to Terminal C from near gate B85 or use the Skyway train on level 3 for connections within the secure area. The subway on level LL provides access outside the secure area.
Construction Update: The Terminal B lobby will close from January 21, 2025, to late 2026. United Airlines passengers flying from Terminals A, B, C, or E should check in at the Terminal C lobby and arrive 2–3 hours early. Gates B3–B31 remain operational, and parking in the A/B garages continues, though Terminal C parking is recommended for easier access. EcoPark shuttles remain available if garages are full.

Level 1 of Terminal B houses the arrivals area with baggage claim and access to ground transportation and parking, ensuring efficient post-flight transitions.
