The San Diego County Regional Airport Authority marked a major milestone with the opening of Phase 1A of the new Terminal 1 at SAN, featuring modern amenities, expanded capacity, and artistic design elements that reflect San Diego’s culture and natural beauty.

The New T1 replaces the 58-year-old Terminal 1 with a modern, world-class facility designed to elevate the passenger experience and meet the growing travel demands of the San Diego region.

Phase 1A of the New T1 features 19 new gates, an expansive ticketing hall with 69 check-in kiosks and 66 ticket counters, a spacious security checkpoint with 13 lanes, seven baggage carrousels capable of handling 4,000 bags per hour, expanded dining and shopping options with 17 restaurants and retail stores, and an outdoor dining area with views of San Diego Bay and downtown.

Sustainability is at the core of the New T1 program. The terminal will run on 100 percent carbon-free electricity.

Construction on Phase 1B of the New T1 will begin in early 2026. Three additional gates will open in Spring 2026, and the remaining eight gates will open in early 2028, bringing the total gates in the new Terminal 1 to 30.
