Getting around LAS
Terminals
Terminal 1 (A, B, C and D gates) and Terminal 3 (D and E gates).
Changing terminals
The two terminal buildings aren't connected outside security, but every gate is linked inside it: trams run between Terminal 1 and the C and D gates, and between Terminal 3 and the D gates.
Customs and international arrivals
Arriving from abroad, you clear U.S. Customs and Border Protection (CBP), collect your checked bags, drop them at the recheck belt and go through TSA security again before your connection. International flights arrive at Terminal 3 (E gates).
