Welcome to the future of travel: San Diego International Airport’s stunning new International Arrivals terminal. With its bold turquoise glass façade and spacious, sunlit entrance, this modern marvel is designed for comfort, flow, and style — setting a new standard for West Coast airports.

Building Design and New Facilities

The terminal now features 19 gates, upgraded passenger amenities, including an outdoor check-in area and more spacious waiting lounges. The project also added an extensive network of roadways and bridges spanning 8 kilometers, along with a parking facility accommodating over 5,000 vehicles, improving circulation within the airport.

Palm trees sway beside glowing jellyfish sculptures, travelers glide through sleek glass walkways, and warm lighting turns arrivals into a welcoming experience. This isn’t just an airport — it’s a gateway to California’s spirit.

Upcoming Phases and Future Expansions

The new terminal is part of a multi-phase architectural project aiming to expand the station to 30 gates across three floors, including a central security checkpoint, departure lounges, airside operational zones, and advanced baggage handling systems.
The next phase will introduce a fully automated baggage handling system, a luminous wave wall, commissioned artworks, and an outdoor dining area with views of the city skyline, creating a fully integrated passenger experience.

Architectural Significance

The new building is designed to accommodate a much higher number of passengers than the previous terminal, emphasizing smooth circulation, user comfort, and the integration of artistic elements in public spaces. Its design embodies a modern approach to airport architecture, balancing aesthetics with functional efficiency.
