George Bush Intercontinental Airport — Houston, United States

Serving as Houston's primary hub for international and long-haul travel, George Bush Intercontinental Airport, designated IAH, sprawls across a large footprint on the city's north side that gives it room for extensive runway and terminal infrastructure. Named for the 41st president of the United States, a Houston resident for much of his post-presidency life, the airport anchors United Airlines' substantial Texas operations and connects the city to destinations across Latin America, Europe, Asia, and the Middle East. IAH has grown alongside Houston's energy industry, ferrying executives and oil-field workers on routes tied closely to the global petroleum trade, particularly connections to Latin American producing nations. Multiple terminals link via an internal train system, and ongoing expansion projects have periodically added gates and improved arrivals facilities to keep pace with growth.
