Overview of George Bush Intercontinental Airport

Named after the 41st U.S. President, IAH is located around 23 miles (37 km) north of downtown Houston. It's one of the busiest airports in the United States, handling more than 48 million passengers in 2024 — up around 7% on pre-pandemic levels — and serves as a major connecting point between the Americas, Europe and beyond.

Where George Bush Intercontinental Connects To

IAH's route network spans domestic U.S. cities alongside extensive international service to Latin America, Europe, the Middle East and Asia. Compare current routes and airlines on Traveloka rather than relying on a single carrier, as schedules and capacity vary by season.

Airlines and Hubs

United Airlines operates IAH as its second-largest hub, running more than 450 daily departures from the airport — the large majority of all flights here. Terminal E is used exclusively by United for domestic and international service, and together with Terminal C it handles nearly three-quarters of all airport traffic.

Terminals at IAH

IAH has five terminals — A, B, C, D and E. All are connected by the Skyway, an above-ground automated people-mover that runs post-security every two minutes, taking around four minutes end to end, plus an older underground subway system. Because United's operations are spread across Terminals C, D and E, allow extra time if you have a connecting flight between terminals.

Getting To and From Downtown Houston

Houston's METRO bus service connects IAH to downtown, and rideshare services (Uber, Lyft) and taxis are available from designated pick-up zones outside each terminal. There is no direct rail line to the airport, so allow extra time for the 23-mile road journey, especially in Houston's peak-hour traffic. Confirm current travel times before you fly.

Facilities at George Bush Intercontinental

As a major U.S. hub, IAH offers extensive traveller facilities.

• A wide range of dining, from quick bites to sit-down restaurants, across all terminals.
• Retail stores, duty-free shopping and airline lounges.
• Free Wi-Fi, charging stations and family-friendly play areas.
