Be at the Airport Well Before Departure:

  • For Domestic Flights: You must reach around two hours before your flight departs. 
  • For International Flights: Reach the airport three hours before your flight. Checking your bags and getting your international papers checked takes extra time.

Getting Between Terminals If You Get Lost:

Landed at the wrong IAH terminal? No need to stress. Just hop on one of the two free airport trains. They run constantly to get you back on track fast. 

  • The Subway: If you need another check-in counter before security, go downstairs to the Lower Level. Take the subway from there. It easily connects all five terminals, making it quick and simple to get exactly where you need to go.
  • The Skyway: Gate changed to another terminal after security? No big deal. Just go up to Level 3. You can catch the free, elevated Skyway train there. It stays inside the secure area and will get you to your new terminal in just minutes.
