SAN DIEGO, CA — San Diego International Airport welcomed 25.32 million passengers last year, marking the airport's busiest ever year.

The growth in 2025 is a 0.3% increase over 2024, which set the previous record.

"SAN has once again surpassed its highest recorded passenger volume," said Kimberly Becker, president and CEO of the San Diego County Regional Airport Authority. "With the opening of our new Terminal 1 and continued expansion of airline service, 2025 stands out as a truly exceptional year."

Contributing to growth in 2025, San Diego International Airport added 14 new routes over five carriers:

• Alaska Airlines: Phoenix, Arizona; Washington, D.C.; Chicago, Illinois; Denver, Colorado; Medford, Oregon; and Sun Valley, Idaho
• Copa Airlines: Panama City, Panama
• Frontier Airlines: Austin, Texas and Salt Lake City, Utah
• KLM: Amsterdam, Netherlands

International travel increased 8% from 2024, fueled by flights to Panama and the Netherlands, as well as expanded service by Lufthansa and Japan Airlines.

San Diego International Airport opened its new Terminal 1 in October, increasing passenger volume by 11% in the last three months of the year compared to the same period in 2024 with the old terminal. JetBlue and Breeze Airways relocated from Terminal 2 to Terminal 1 following its opening.
