The airport has two terminals, Terminal 1 and Terminal 2, which are right next to each other
San Diego International Airport is a compact airport located just three miles from downtown San Diego. The airport is currently undergoing construction, with Terminal 1 being torn down and rebuilt to modern standards, similar to the new part of Terminal 2. Despite the construction, the airport is generally easy to navigate, with clear signage and a small size that makes it convenient for passengers to move between the two terminals.
Both terminals offer valet parking, which can be convenient for travellers in a hurry. However, it is recommended to arrive at the airport well ahead of your flight time, especially during commuter rush hours, busy weekends, and holidays, when security lines and check-in counters can become crowded. On average, passengers can expect to spend about 15 minutes in the security line, but this can vary depending on the time of day and day of the week.
To expedite the security process, passengers can sign up for the Transportation Security Administration's (TSA) PreCheck program, which allows for faster clearance without the need to remove shoes, laptops, or liquids. For those without PreCheck, it is advisable to wear easily removable shoes and to organise carry-on luggage neatly to facilitate a smoother inspection process.
Overall, while San Diego International Airport is undergoing enhancements, its compact size and convenient terminal layout make it a passenger-friendly airport. The ongoing construction aims to further improve the airport's functionality and aesthetics, bringing it up to modern standards.

Terminal 2 mainly serves international and regional aircraft and has interconnected concourses
San Diego International Airport (IATA: SAN, ICAO: KSAN, FAA LID: SAN) is located just three miles from downtown San Diego, California. It is the primary international airport serving the city and its surrounding areas. The airport is owned and operated by the San Diego County Regional Airport Authority, which assumed jurisdiction in December 2002. The airport was previously known as Lindbergh Field until the authority changed the name in 2003 to better reflect its status as a major commercial airport.
The airport's single runway operates in controlled airspace served by Southern California TRACON. While it is the busiest single-runway airport in the United States, it has a challenging landing approach due to its proximity to downtown San Diego's skyscrapers and the steep descent angle.
San Diego International Airport has been the subject of relocation proposals over the years, but these have been defeated, leading to a focus on improving existing facilities. The airport implemented a curfew in 1979 to address noise concerns, restricting takeoffs to between 6:30 a.m. and 11:30 p.m., with exceptions for specific types of aircraft.
