SAN San Diego Airport Guide: Everything You Need to Know

SAN Airport Overview

San Diego International Airport is one of the most conveniently located airports in the country. It sits on the edge of San Diego Bay, just 3 miles from downtown, with runway approaches that give you stunning views of the city skyline and Coronado Bridge. It handles about 27 million passengers a year through two terminals.

SAN is a single-runway commercial airport, which is remarkable given its traffic volume. This means delays can cascade quickly during bad weather or heavy traffic periods. But the tradeoff is an airport that's compact, easy to navigate, and absurdly close to everything San Diego has to offer.

Terminal and Concourse Layout

SAN has two terminals. They're close together but getting between them airside requires either a shuttle or re-clearing security.

Terminal 1

The older terminal with three concourses. Handles a mix of domestic carriers including Southwest (the largest carrier at SAN), Frontier, Hawaiian Airlines, and others. Each concourse has a separate security checkpoint. Terminal 1 has been undergoing renovations, with a major new Terminal 1 project adding modern facilities.

Terminal 2

The newer, larger terminal with two concourses: East and West. Serves Alaska Airlines, American, Delta, JetBlue, Spirit, United, and international flights. Terminal 2 has better dining, more lounges, and newer amenities overall. If you have a choice, Terminal 2 is the more comfortable experience.

Getting Between Terminals

A free shuttle bus runs between terminals 24/7/365. The ride takes about 5 minutes. There's also a pedestrian sidewalk connecting them, but it's a 10-15 minute walk outdoors and you'll need to re-clear security at your destination terminal. If connecting between terminals, budget at least 45-60 minutes to account for the shuttle and security.

Getting To and From San Diego

Route 992 "The Flyer" (Best Budget Option)

This express bus connects both terminals to downtown San Diego in 10-15 minutes for $2.50. It runs every 15-20 minutes and stops at major downtown locations including the Santa Fe Depot transit center. From there, you can connect to the San Diego Trolley, Amtrak, and Coaster commuter trains. This is hands-down the best value for getting downtown.

Rideshare (Uber/Lyft)

Pickup is at designated areas on the ground level. Downtown San Diego is $10-$18. La Jolla is $25-$35. The Gaslamp Quarter is $10-$15. Pacific Beach is $15-$22. Given how close SAN is to everything, rideshare costs are lower than at most airports.

Taxi

Taxis queue at the ground level of each terminal. Downtown San Diego is about $12-$18 on the meter. La Jolla runs $30-$40.

Rental Cars

All rental companies are consolidated at the Rental Car Center across from the terminals. The free Airport Loop shuttle provides constant service between the terminals and the Rental Car Center. The shuttle runs frequently and the ride is just a few minutes.

San Diego Trolley

The trolley doesn't serve the airport directly, but you can take Route 992 to the Santa Fe Depot and transfer to the Blue, Green, or Orange trolley lines from there. The trolley is great for reaching Old Town, Mission Valley, and the Mexican border.

Lounges

All lounges at SAN are in Terminal 2. Terminal 1 has no lounge access.

• Aspire Lounge (Terminal 2) - The best option for travelers without airline-specific lounge access. Open to Priority Pass members and walk-ins ($50 day pass). Serves complimentary food and drinks, has WiFi, and offers runway views. Gets crowded in the afternoons.
• Delta Sky Club (Terminal 2) - For Delta Sky Club members and eligible Delta passengers. Standard Delta Sky Club amenities.
• United Club (Terminal 2) - For United Club members and eligible United passengers.
• USO Lounge (Terminal 2) - Free for active military and their families. One of the better USO lounges in the country.

If you're departing from Terminal 1, there are no lounge options. Plan accordingly - eat, hydrate, and charge up before clearing security.

Food and Dining

SAN's food scene reflects San Diego's culinary identity: craft beer, fish tacos, and California-fresh ingredients.

Don't Miss

• Stone Brewing Tap Room (Terminal 2) - San Diego is the craft beer capital of America, and Stone Brewing brings that culture into the airport. Locally brewed IPAs, pale ales, and seasonal beers on tap, plus gourmet burgers and artisanal pizzas. A must-visit even if you're not a beer enthusiast.
• Carnitas' Snack Shack (Terminal 2, near Gate 37) - Famous for slow-roasted pork carnitas, fish tacos, and California-style breakfast burritos. A San Diego institution. The Triple Threat Pork Sandwich is legendary.

Quick Bites

Terminal 2 has the wider variety: Starbucks, Phil's BBQ (another San Diego staple), panini shops, and grab-and-go salad places. Terminal 1's food options are more limited and rely more heavily on chains, though the ongoing renovations are adding new concepts.

Late Night

No 24-hour dining at SAN. Most restaurants close with the last flights. Vending machines with drinks and snacks are available throughout both terminals.

WiFi

SAN offers free WiFi. Connect to the "#SANfreewifi" network. You get two hours of free access, then need to watch a short ad to restart the session. You can repeat this as many times as needed, so it's effectively unlimited with a minor annoyance every two hours. Speeds are fine for browsing and email. Power outlets and USB ports are available at many seating areas. FuelRod portable charging kiosks are also available for purchase.

Sleeping at SAN

The Reality

SAN is not an overnight airport. Airside areas close after the last flight arrives (typically around midnight), and everyone is moved to the landside areas. Security doesn't reopen until around 5 AM. There are no sleep pods, no Minute Suites, and no airside hotel.

If You're Stuck

Terminal 2 has newer couches, padded benches, and some armless chairs that work for napping during daytime layovers. For overnight stays, you'll be in the pre-security landside areas, which are brightly lit and have frequent announcements. Airport staff generally tolerate overnight sleepers as long as you stay in the landside areas.

Bring an eye mask, earplugs, and warm layers. The airport gets cold at night and the lights never go off. Luggage storage and lockers are not available at SAN.

Nearby Hotels

The good news is that several hotels are very close. The Courtyard by Marriott Liberty Station is about 5 minutes away. The Hilton San Diego Airport/Harbor Island has great bay views and runs a free shuttle. The Sheraton San Diego Hotel & Marina is also nearby with shuttle service.

Layover Tips

• Short layover (under 2 hours): If both flights are in the same terminal, connections are easy - SAN is compact. If you're switching terminals, the shuttle and security can eat into your time. Budget 45-60 minutes for terminal transfers.
• Medium layover (2-5 hours): Stone Brewing is mandatory. Carnitas' Snack Shack is a close second. If you have Aspire Lounge access, settle in with a drink and enjoy the runway views.
• Long layover (5+ hours): SAN's location is your advantage here. Take a rideshare to the Gaslamp Quarter (10 minutes, $10-$15) for restaurants, bars, and shopping. Head to Old Town for Mexican food and history. Hit Pacific Beach or La Jolla for ocean views. Balboa Park and the San Diego Zoo are 15 minutes away. Leave 1-1.5 hours for the return trip and security - SAN's proximity to everything makes these trips very doable.
• One-runway reality: SAN operates on a single runway, so delays can stack up during busy periods or when weather moves in. Build buffer time into your plans and don't count on split-second connections.
• Terminal 1 tip: Terminal 1 is being renovated. Check construction updates before you fly, as some areas may be temporarily limited in food and amenity options.
