Houston has three major airports and maps for all of them are available at Fly2Houston.com. The George Bush Intercontinental Airport is the city's largest airport and offers both domestic and international non-stop flights.
The William P. Hobby Airport is the second largest in the city and offers service to cities throughout the United States. It is set to begin providing international flights in October 2015.
The Ellington Airport is the smallest of the three. It services the U.S. military, NASA and general aviation. While the airport was originally commissioned as a military aviation training facility, the newest runway as of 2015 can accommodate medium-sized business jets.
