What to know
Southwest has a large LAS operation, so leave time to walk to the far end of the assigned concourse.
Airport layout
LAS uses Terminals 1 and 3. The D gates sit between them and can be reached from either side, but baggage claim follows the airline's assigned terminal.
Getting to the gate
Use the airline's listed terminal for check-in and pickup even when the gate itself begins with D.
Connections
Trams link the gate areas, but there is no pedestrian route between Terminals 1 and 3 outside security.
