The best way to navigate through either of Houston's main airports is to use the Fly2Houston mobile website. The site features overview maps for each airport, as well as detailed maps of each terminal.
As of 2015, the main Fly2Houston mobile page provides two links: one for George Bush Intercontinental Airport (IAH) and one for the William P. Hobby Airport (HOU). Within each section, travelers can click on the Maps and Directions link to display a list of maps. Passengers flying through HOU, which has just one terminal, can use the Ticketing Level map to find the correct check-in counter, gate or food option. The Baggage Level map shows ground transportation options, bathrooms and services.
Because IAH is considerably larger, arriving travelers should use the overall airport map to find their position, concourse locations, InterTerminal Train stops and TerminalLink stops. One a traveler is in the correct terminal, the individual terminal maps show gate locations, restaurants, shops and service locations.
Fly2Houston offers other information that is helpful for passengers, including parking lot locations, rates and available spots. Travelers can use the Dine, Shop, Services section to search for a list of options by terminal. For people navigating around the exterior of the airport, the Passenger Pick Up Wait Lot section provides a map and a flight-search tool.
