San Diego International Airport (SAN) — officially named San Diego International Airport but still often called Lindbergh Field after pioneering aviator Charles Lindbergh, who was born in San Diego — is the primary commercial airport serving the greater San Diego metropolitan area and one of the most unusually situated major airports in the United States. Located on San Diego Bay just two miles from downtown San Diego, SAN serves millions of passengers annually despite operating from a single runway — making it one of the busiest single-runway airports in the world.
San Diego International Airport occupies a narrow strip of land on the northern shore of San Diego Bay, hemmed in by downtown San Diego to the east, San Diego Bay to the south, and a hillside residential neighborhood to the north. This constrained geography means the airport operates with a single runway of 9,401 feet — a remarkable constraint for an airport handling more than 25 million passengers annually in peak years.
The airport's approach is one of the most dramatic in commercial aviation. Aircraft landing on Runway 27 make a final approach that passes directly over downtown San Diego at low altitude, providing spectacular views of the city's skyline and bay for arriving passengers — and equally spectacular (if sometimes startling) views of low-flying aircraft for downtown residents and visitors.
Terminal 2 is the primary facility and handles major domestic and international operations. Terminal 1 has been demolished and is being entirely rebuilt in a major capital project that will significantly expand SAN's capacity and modernize its facilities.
San Diego's first commercial airport was established in 1928 at the current site and named for Charles Lindbergh, who had departed from San Diego on the first leg of his transatlantic flight in the Spirit of St. Louis the previous year. The airport has carried the Lindbergh Field name informally ever since, even after the formal renaming to San Diego International Airport.
The airport's single-runway configuration has always been both a defining characteristic and a limiting factor. Multiple proposals over the decades to expand the airport's site or build a replacement airport at a less constrained location have been studied but none have succeeded, leaving SAN to maximize efficiency within its existing footprint. Terminal 2 was expanded and modernized in the 2010s. The current New T1 project, launched in the early 2020s, is replacing Terminal 1 with a substantially larger and more modern facility.
SAN currently operates primarily from Terminal 2, a multi-gate facility handling Southwest Airlines, Delta Air Lines, American Airlines, United Airlines, and international carriers. Terminal 2 West and Terminal 2 East are distinct sections of the same building, connected on the airside. Terminal 2 is fully operational while Terminal 1 is being rebuilt.
The new Terminal 1 project, expected to open in phases, will be a modern 30-gate facility replacing the previous smaller building. When complete, the new T1 will significantly increase SAN's total gate count and passenger capacity. An underground connector between the two terminals is planned to provide airside connectivity.
Southwest Airlines is the largest carrier at SAN by seat count and operates extensive domestic service from Terminal 2. Delta Air Lines, American Airlines, and United Airlines all have significant domestic operations at SAN. Alaska Airlines serves multiple West Coast routes.
International service at SAN is limited by the airport's single-runway capacity constraints but includes routes to Mexico, Japan (Japan Airlines nonstop to Tokyo), and several other international destinations. British Airways, Lufthansa, and select other carriers have operated seasonal international routes. SAN provides nonstop service to approximately 60 destinations.
Terminal 2 features a solid selection of San Diego-themed dining and retail, with local restaurant brands and a generally pleasant Southern California atmosphere. The terminal has been upgraded in recent years with improved gate areas and amenities. Free Wi-Fi is available throughout. Airline lounges for Delta and American operate in Terminal 2.
The new Terminal 1, when complete, will significantly raise the amenity bar at SAN with a substantially larger and more modern facility. The scenic location adjacent to San Diego Bay provides pleasant outdoor viewing areas near the terminal roadway.
SAN does not currently have a direct connection to San Diego's trolley system, though a planned Airport Connector light rail project has been studied and is in various stages of planning and environmental review. Current transit options include MTS Route 992, which connects the airport to the Old Town Transit Center (a major trolley hub) in approximately 10 minutes, providing connections to the Blue and Green Trolley lines and downtown San Diego.
Rideshare services are among the most popular ground transportation options at SAN given its proximity to downtown San Diego. The drive to downtown is approximately 5–10 minutes. Taxis serve the airport. The Rental Car Center, called the new Rental Car Center, is connected to the terminal via the SAN Ground Transportation Center.
SAN provides parking in structures adjacent to both terminals and in economy lots with shuttle service. The proximity to downtown San Diego makes rideshare a particularly practical option, and many travelers from central San Diego neighborhoods opt for rideshare rather than parking. Parking reservations are recommended during peak summer travel periods when San Diego's tourism peaks.
The single runway at SAN means the airport can experience departure delays when arrival traffic is heavy, as aircraft must share a single runway for both takeoffs and landings. Morning departures are generally more reliable than afternoon flights. The spectacular approach over downtown San Diego on Runway 27 puts aircraft at very low altitude over the Hillcrest neighborhood — window seats on the right side of the aircraft (for eastbound landings) provide striking views.
The airport's compact size and proximity to downtown mean that door-to-gate times are shorter than at most major airports. Security lines at Terminal 2 can be long during busy summer periods — arrive at least 90 minutes before domestic departures.
San Diego International Airport is the primary air travel infrastructure for the San Diego metropolitan area — a major city of more than 3 million people in one of the country's most important defense, biotechnology, tourism, and technology corridors. The airport directly enables San Diego's military defense industry (the largest in the country), its burgeoning biotech and healthcare sectors, and its substantial tourism economy anchored by beaches, the zoo, and the climate.
The airport's single-runway constraint is both an operational limitation and an economic one — it limits San Diego's air service options relative to peer cities and forces airlines to make difficult capacity decisions. The New T1 project addresses the facility limitation; the runway constraint remains a long-term structural challenge for the airport.
The New Terminal 1 project is SAN's primary near-term development initiative, adding substantial gate count and modern facilities. A long-term Airport Connector light rail project, if funded and built, would provide the first direct rail link between SAN and the regional transit network. Environmental studies for various airport expansion and ground transportation connectivity scenarios continue. The airport authority is also pursuing sustainability programs consistent with California's aggressive environmental goals.
SAN is a primary commercial airport and a major regional gateway for Southern California. It provides essential domestic and limited international connectivity for the San Diego metropolitan area despite operating from a uniquely constrained single-runway site.

San Diego International Airport is one of the most distinctive major airports in the United States — constrained by geography yet remarkably efficient, famous for its dramatic downtown approach, and poised for its most significant infrastructure expansion in decades with the new Terminal 1. For a city of San Diego's size and economic significance, the airport punches above its weight in connectivity, and its proximity to downtown makes it one of the most convenient major airports in California despite its operational limitations.
San Diego International Airport is constrained on all sides by San Diego Bay, downtown San Diego, and hillside residential neighborhoods. There is no room to build a second runway within the existing airport footprint, making SAN one of the busiest single-runway airports in the world.
Aircraft landing on Runway 27 at SAN make a straight-in approach from the west over downtown San Diego at low altitude due to the runway's position and length. The approach is one of the most visually dramatic in commercial aviation and is normal for SAN operations.
Not directly. MTS Route 992 bus connects SAN to Old Town Transit Center in approximately 10 minutes, where passengers can transfer to the Blue Line trolley to downtown San Diego. A direct Airport Connector trolley line has been studied but is not yet funded or built.
San Diego International Airport is replacing its previous Terminal 1 with a brand-new, larger modern facility (the New T1 project) that will significantly increase gate capacity and improve passenger amenities. The project is being built in phases.
