Security Checkpoint

Shorter lines

Security checkpoints are busiest on weekday and Sunday mornings and late afternoons. There are two checkpoints on either end of the Main Terminal, but there is a third smaller checkpoint on the Baggage Claim level. It is for passengers heading to Z Gates so it is not as busy as the main checkpoints; however, you can take the Aerotrain from the Z Gates to Concourses A and C.

The Kids' FunWay admits children younger than 12 years and no taller than 42 inches (106 cm).
