San Diego Airports Guide: Terminals, Transport, and Essential Information

San Diego, California, is served by one primary international airport located remarkably close to the city’s downtown and urban core. The region also has several smaller airports catering to general aviation, military operations, and specific cross-border travel. San Diego’s main airport is famous for its single runway operation and spectacular views on approach, flying directly over the city’s neighborhoods.

This guide details the airports serving the San Diego metropolitan area, including terminal layouts, ground transportation options, and practical tips for navigating your journey to America’s Finest City.

San Diego International Airport (SAN) – Lindbergh Field

Overview: San Diego International Airport, still commonly called Lindbergh Field, is the primary commercial airport serving the region. Located just 3 miles (5 km) northwest of downtown San Diego, in the neighborhood of Point Loma, it is one of the busiest single-runway commercial airports in the world. Its proximity to the urban core is both a major convenience and an operational constraint.

Terminals:

• Terminal 1: A recently rebuilt, modern terminal housing Gates 1-18. Serves Southwest Airlines, Frontier, and other domestic carriers.
• Terminal 2: Houses Gates 20-51. Serves Alaska Airlines, American, Delta, JetBlue, United, and all international arrivals. The terminal is divided into East (Gates 20-36) and West (Gates 40-51) halls, connected by a long corridor with moving walkways.
• Commuter Terminal (Terminal 2 West): Gates 46-51 are often used for smaller regional jets and turboprops.

The two main terminals are separate buildings. A free, frequent “Airport Loop” shuttle bus connects Terminal 1, Terminal 2, and the Rental Car Center. A pedestrian sidewalk also connects them, but it’s a 10-15 minute walk.

Getting to and from SAN Airport:

• Metropolitan Transit System (MTS) Bus & Trolley:
  • Bus: Route 992 (“The Flyer”) is an express bus connecting both terminals to downtown San Diego (Santa Fe Depot, City College) in about 10-15 minutes. It runs every 15-20 minutes. Fare is $2.50. Other local bus routes (like the 923) also serve the airport.
  • Trolley (Light Rail): The MTS Green Line has a station at the Rental Car Center. From there, a free shuttle bus takes you to the terminals. The trolley connects to downtown, Old Town, and Mission Valley. A more direct trolley connection to the terminals is planned for the future.
• Taxi / Ride-hailing (Uber, Lyft):
  Designated pickup areas are on the Arrivals (lower) level of both terminals. Due to SAN’s proximity, fares are very reasonable. A trip to downtown or the Gaslamp Quarter is typically $15-25 and takes 10-15 minutes. To beaches like Mission Beach or Pacific Beach: $20-35, 15-25 minutes.
• Rental Car:
  All major rental companies are consolidated in a single Rental Car Center across from the terminals. The free Airport Loop shuttle provides constant service to/from this center.
• Hotel Shuttles:
  Many area hotels offer complimentary shuttle service; pick-up is typically on the upper (Departures) level at designated curbside zones. Confirm with your hotel.
• Driving & Parking:
  Parking is available but can be expensive and fill up during peak periods. Options include Hourly Parking (closest, $4/hr), Daily Parking (in each terminal’s garage, $32/day), and the more economical Park & Ride Lot ($20/day) with a shuttle.

Best for: All commercial airline travelers, visitors to downtown San Diego, Balboa Park, the Gaslamp Quarter, and coastal neighborhoods.

San Diego’s Other Airports (Non-Commercial)

General Aviation & Military:

• Montgomery Field (MYF): A busy general aviation airport located in the Kearny Mesa area, about 8 miles northeast of downtown. Used for private planes, flight training, air charters, and air ambulances. No scheduled passenger service.
• Brown Field Municipal Airport (SDM): Located near the US-Mexico border in Otay Mesa. Primarily used for general aviation, cargo, and flight training. Known as a port of entry for private aircraft arriving from Mexico.
• Marine Corps Air Station Miramar (NKX): A major US Marine Corps installation famous as the former home of the “Top Gun” flight school. Not open to civilian passenger travel.
• North Island Naval Air Station (NZY): A US Navy base on Coronado. No civilian access.

Tijuana International Airport (TIJ) – Cross-Border Option

Overview: While not in the US, Tijuana International Airport in Mexico is a significant travel option for San Diego residents and savvy visitors. It offers an extensive network of low-cost and domestic Mexican flights, often at fares dramatically lower than from SAN. A unique, official Cross Border Xpress (CBX) pedestrian bridge connects a terminal on the US side directly to TIJ.

How CBX Works:

1. Purchase a CBX bridge ticket online or at the facility (approx. $18-25 USD one-way).
2. Arrive at the CBX terminal on the US side (located immediately adjacent to the Otay Mesa border crossing).
3. Clear US exit formalities, walk the enclosed, secure bridge (about 10-15 minutes).
4. Arrive directly inside the TIJ airport terminal, ready for check-in.

The reverse process brings you from your TIJ arrival back to the US, where you clear US Customs and Immigration at the CBX facility.

Getting to CBX: Located about 20 miles southeast of downtown San Diego. Accessible by taxi/rideshare (approx. $40-50 from downtown), rental car (parking available), or MTS bus route 225.

Best for: Travelers flying to destinations within Mexico, Central/South America on Mexican carriers (Volaris, Viva Aerobus, Aeroméxico), and those seeking substantial cost savings on certain routes.

Which San Diego Airport Should You Choose?

San Diego International Airport (SAN) is the best and only choice for the vast majority of travelers, especially those visiting San Diego itself. Its unparalleled convenience cannot be overstated.

Tijuana Airport (TIJ) via CBX is a strategic alternative for:

• Flights deep into Mexico (e.g., Mexico City, Guadalajara, Cancún).
• Travel to Central/South America on low-cost Mexican carriers.
• When fares from SAN are prohibitively high.

Only choose this if the savings are significant and you are comfortable with the border-crossing process.

Montgomery & Brown Fields are only for private/charter aviation.

Military Air Stations are not options for civilian travel.

Airport Transfers and Regional Transportation

To Downtown & Urban Core: SAN’s proximity makes ride-hailing, taxis, or the MTS 992 bus all excellent options. The drive is rarely longer than 15 minutes outside of peak rush hour.

To Major Attractions & Neighborhoods:

• Balboa Park/Zoo: 10-15 minute drive or take the 215 bus from downtown.
• SeaWorld: 10 minute drive from SAN or take the 9 bus.

Old Town San Diego: 5-10 minute drive or take the Green Line trolley from the Rental Car Center.

• La Jolla: 20-30 minute drive north.
• Coronado: 10-15 minute drive (plus bridge or ferry) or take the 901 bus to the ferry terminal.

To Other Southern California Cities:

• Amtrak / Coaster Commuter Rail:
  The Pacific Surfliner and Coaster trains stop at the Santa Fe Depot downtown, easily reached from SAN via the 992 bus or taxi. Scenic route to Orange County and Los Angeles.
• FlixBus / Greyhound:
  Bus services to Los Angeles, Anaheim, Phoenix, etc., depart from the downtown bus station.
• Rental Car:
  I-5 and I-8 connect San Diego to Los Angeles (2+ hours), Orange County (1.5 hours), and the desert/ Arizona.

Practical Tips for San Diego International (SAN):

• Single Runway Delays: Weather (marine layer fog) or incidents can cause significant delays due to the single runway. Allow buffer time for afternoon/evening departures.
• Terminal Check: Always confirm your terminal (T1 or T2) before arriving, as the shuttle bus between them adds time.
• Views on Approach: For the best views of the city, request a window seat on the left (A) side of the aircraft when landing from the east.
• Food: SAN has excellent local food options (Phil’s BBQ, Stone Brewing, etc.). Eat before your flight.
• Rental Car Shuttle: Allow an extra 20-30 minutes to take the shuttle to the Rental Car Center, check in, and get your car.

Bottom line: San Diego International Airport (SAN) is the premier choice for its unmatched convenience. Use a taxi or rideshare for the quick, inexpensive trip downtown, or the MTS 992 bus for great value. Only consider the Tijuana (TIJ)/CBX option for substantial savings on specific routes to Mexico and beyond, factoring in the extra time and cost of reaching the border crossing.
