The subway station is near the entrance to the passenger walkway and B gates.

    It can be reached by a walkway from the main terminal, by AeroTrain connecting either to the main terminal or to the C Gates in the second terminal building or by a shuttle service connecting A and C Gates as well as A and Z Gates
  • the other terminal contains C and D gates, operating all United Airlines flights.

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.
