San Diego airport overview
Sometimes referred to as Lindbergh Field, San Diego International Airport is located 4.8km (3 miles) northwest of the centre of the city of San Diego, at the southern tip of California.
It is the United States’ busiest single runway commercial airport, handling around 18 million passengers per year. As it’s situated within a highly populated suburban area, departures are only permitted between 6:30am and 11:30pm.
San Diego International has three terminals: Terminals 1 and 2 and the Commuter Terminal. All international arrivals are handled by Terminal 2, while the Commuter Terminal services flights between San Diego and Los Angeles International Airport. The airport is relatively easy to navigate and flights are generally punctual during most of the year, however delays are common in autumn and winter when visibility is low (thanks to the mighty Santa Ana winds that sweep through the region).
Despite having only one runway, San Diego International manages to keep up with the number of passengers frequenting its terminals each year. It’s a small and clean airport with helpful staff and sufficient amenities.
