San Diego Airport Thrives with New Terminal 1 Expansion and Increased International Routes
The new Terminal 1 at San Diego International Airport is leveraging modern facilities and strategic routes to drive growth despite broader tourism challenges in California.
Terminal 1 Expansion Bolsters San Diego Airport
The launch of Terminal 1 is a milestone in San Diego’s $3.8 billion airport improvement plan. It aims to enhance passenger experience and growth potential.
San Diego International stands out in a climate where California airports struggle with diminishing international travel. The airport saw a 5.5% increase in international travelers over the past year.
New International Routes
- Direct flights to Amsterdam via KLM Royal Dutch Airlines began in May.
- Copa Airlines introduced a route to Panama in June, offering new access to South America.
- London flights doubled, with the airport offering two daily non-stop flights.
These additions are attributed as key factors in the airport’s growth, even as domestic airlines absorb a significant share of outgoing travel.
Wider Travel Landscape
While San Diego thrives, the broader picture for California’s international tourism is less positive. Canadian visits dropped nearly 38% between August 2024 and 2025. Japanese and Australian tourism also decreased.
Governor Gavin Newsom has initiated campaigns to attract tourists back to the state, stressing California’s welcoming climate and attractions.
| Country | Change in Visits |
|---|---|
| Canada | -38% |
| Japan | -20% |
| Australia | -15% |
San Diego’s Resilience and Future Prospects
The regional airport authority predicts the expansion to generate $7.4 billion in sales and $127 million in local taxes through 2029. San Diego maintains a smaller decline in passenger numbers than Los Angeles International, showing its capacity to adapt.
Despite predicted downturns in tourism, San Diego’s continued infrastructure development and diverse route options offer hope for sustained growth in international traffic.
