San Diego International Airport (SAN) is one of the closest big-city airports to its downtown in the country, sitting only about 2 miles from Downtown San Diego.
Two Terminals, Short Walk Between Them
SAN has two terminals, 1 and 2, close enough together that connecting on foot is realistic for most travelers, without needing an airport train.
No Trolley Stop, But Easy Bus Connections
The San Diego Trolley does not stop at the airport itself, but Route 992 serves both terminals and reaches a Trolley connection downtown in under 15 minutes, and the San Diego Flyer shuttle reaches Middletown Station on the Blue or Green Line in about the same time.
A Short, Simple Trip Either Way
Between the short distance and multiple transit options, SAN is one of the easier US airports to reach downtown from without a car, even without a direct rail link.
