Know exactly what to do at the airport.

What do I do next? We'll tell you.

• Passport control

  Whether you clear immigration — or U.S. Preclearance — before your gate.

• Baggage

  Whether your bags are transferred, or you need to collect and recheck them.

• Security

  Whether you're screened again on the way to your next flight.

• Terminal changes

  When you change terminals, and how to get there.

We only state procedures we've verified from official airport and government sources. When we can't confirm something, we say so — and point you to the official resource.
