SAN at a glance
San Diego International is a single-runway airport close to the city center. Its two terminals are not connected airside, and that is the most important thing to plan for on a trip that includes both.
Terminal 1 is the first phase of a multi-billion dollar rebuild and opened in September 2025 with 19 gates, a 13-lane checkpoint and an outdoor deck with views of the bay. It has no lounges. Terminal 2 has all four airside lounges.
Main airlines: Alaska Airlines and American Airlines check in at Terminal 2 East. Delta, United, Hawaiian and the international carriers operate from Terminal 2 West. Check your airline on the departures board, since gate assignments are split across the two terminals.

Late departures by month
Terminals
Terminal 2 East
Home of the Aspire Lounge, between gates 23 and 33. Alaska and American check in here.
Terminal 2 West
Delta, United, Hawaiian and the international carriers operate here. The Chase Sapphire Lounge is between gates 46 and 47, and the Delta Sky Club and United Club are on the mezzanine.
Moving between terminals
The two terminals do not connect airside. The free Inter-Terminal Shuttle runs between Terminal 1 and Terminal 2 from about 4 a.m. to 2 a.m., and it may take longer during construction. Changing terminals means leaving security and going through the checkpoint again, so allow at least 45 minutes for the trip.
