San Diego Airport (SAN) | Terminal maps

serves primarily domestic flights and is currently undergoing a significant redevelopment project that will eventually replace the original 1960s-era building. At present, Terminal 1 operates with 14 gates, with 19 new gates expected to open by late 2025 and a total of 30 gates planned by 2028.

Southwest Airlines is the primary operator at Terminal 1, along with other domestic carriers like Frontier, Spirit, JetBlue, Allegiant, and Sun Country. The terminal is divided into three separate concourses: gates 1, 1A, and 2 in the east rotunda; gates 3–10 in the central concourse; and gates 11–18 in the west concourse. Each concourse has its own security checkpoint, and they are not connected beyond security, so it’s essential to use the correct checkpoint for your gate.

Dining options in Terminal 1 include quick-service outlets like Jack in the Box, Ciao Gourmet Market for salads and sandwiches, and local favorite Bankers Hill Bar & Market near Gate 7. Coffee shops and snack stands are available, though the selection is more limited compared to Terminal 2.

There are no lounges in Terminal 1. Passengers wait in gate areas with seating, power outlets, and water refill stations. Future phases of the New T1 project are expected to introduce more premium amenities. For now, travelers looking for lounge access must use Terminal 2.

Security at Terminal 1 can be busy, especially in the mornings. Passengers should plan to arrive at least 90 minutes before domestic flights, or two hours during peak periods. TSA PreCheck is available, but CLEAR service is not offered. Check-in counters usually open around 4:30 AM, and gates are easy to locate once past security.

Terminal 1 and Terminal 2 are a short five-minute walk apart, and a free shuttle service is available. Be aware that transitioning between terminals means exiting and re-entering through TSA screening.

For families, Terminal 1 includes lactation rooms in both east and west concourses and several family restrooms. While there’s no formal play area, there is a pet relief zone outside at the curbside Zone A. The terminal is accessible, with wheelchair assistance available upon request.

is the larger and more modern terminal, handling both domestic and all international flights. It features two connected concourses – East and West – with a total of 32 gates (numbered 20–51). Unlike Terminal 1, Terminal 2’s concourses are connected post-security, so passengers can access all gates once through screening.

Airlines operating from Terminal 2 include American Airlines, Alaska Airlines, Delta, United, British Airways, Japan Airlines, Air Canada, Lufthansa, and other international carriers. Most domestic flights not operated by Southwest Airlines also depart from Terminal 2.

Dining options in Terminal 2 are varied and abundant. In the central Sunset Cove food court, travelers can choose from restaurants like Asian Kitchen and local favorite Stone Brewing near Gate 46. There are also Italian eateries, coffee shops, and snack counters located throughout both concourses.

Terminal 2 hosts all four airport lounges: the Aspire Lounge near Gate 23, the Chase Sapphire Lounge at Gate 46, Delta Sky Club, and United Club. Access depends on airline, ticket class, or lounge memberships.

Security checkpoints are efficient, with large screening areas on both East and West sides of the terminal. TSA PreCheck is available, and CLEAR lanes operate in Terminal 2. For international flights, it is recommended to arrive three hours early, and two hours for domestic departures.

Walking between Terminal 1 and Terminal 2 is quick and straightforward, but keep in mind the need to go through security again when switching terminals. A free shuttle bus also runs between them.

Family-friendly features include a nursing room near Gate 34, multiple family restrooms, and a pet relief area inside Terminal 2 near Gate 47. While there is no dedicated kids’ play zone, there are open areas and large windows that make it easier to entertain children. The terminal is ADA-compliant, with ramps, elevators, moving walkways, and accessible seating throughout. Wheelchair services are available through the airlines and should be requested in advance or at check-in.
