George Bush Intercontinental Airport (IAH) in Houston is United Airlines' second largest hub and one of the top gateways for international travel from the southern United States. The combination of United's global network and aggressive competition from Spirit, Frontier, and international carriers makes IAH one of the most rewarding airports for deal seekers.
Why IAH delivers world class deals
United Airlines operates over 600 daily flights from IAH, serving destinations across six continents. That massive network creates constant fare competition, especially on routes where other carriers overlap. When United runs a fare sale from Houston, it ripples through the market and competing airlines match or beat the price.
Houston's geographic position as a gateway between the U.S. And Latin America also means exceptional deals southbound. Mexican and Central American destinations see some of the lowest fares from any U.S. Airport.
Airlines serving IAH
United Airlines dominates with global service across 200+ destinations. Spirit Airlines competes aggressively on domestic and Caribbean routes. Frontier Airlines targets leisure destinations. Emirates offers nonstop to Dubai. Qatar Airways serves Doha with connections to Asia and Africa. Lufthansa connects to Frankfurt. All Nippon Airways serves Tokyo. Aeromexico, Volaris, and VivaAerobus cover Mexico extensively.
Top deal routes from IAH
Latin America deals are IAH's strongest suit: Cancun from $119 round trip, Mexico City from $149, Bogota from $199, Lima from $249, and Buenos Aires from $349. Domestic routes see regular deals too: New York from $79, Los Angeles from $99, Chicago from $69. Transatlantic deals include London from $349, Frankfurt from $389, and occasionally sub $400 fares to Asia through Middle East connections.
IAH vs Houston Hobby (HOU)
Houston has two major airports. IAH handles all international flights and United's hub operations. Hobby Airport (HOU) is Southwest's territory with domestic and some Caribbean/Mexico routes. For maximum deal coverage, we recommend adding both to your Early Bird Air profile.
Navigating IAH
IAH has five terminals. Terminals A and B handle most United domestic flights. Terminal C is United's international hub. Terminal D serves partner airlines. Terminal E handles international arrivals and other carriers. The Skyway train connects all terminals and runs frequently.
Pro tip: IAH's Terminal C has some of the best United Club lounges in the system, including a Polaris lounge for business class passengers.
