San Diego Airport Guide

SAN Airport Overview

To help you plan your layover or overnight sleepover, here is a quick run-down about what to expect during your time at San Diego International Airport.

What to Expect

San Diego Airport (Code: SAN) is separated into Terminals 1 and 2, which are easy to stroll between on the landside. There is a mix of local and well-known shops and eateries, though most close for the night. Vending machines are the only overnight food options. WiFi is free, though it is limited to 2-hour sessions. Economy class travellers who want to upgrade their layover can pay to enter a few airport lounges; one even has shower facilities.

Sleeping in San Diego Airport

After security checkpoints close for the night, passengers are restricted to landside only. Passengers sleeping airside will be required to return to the landside until security reopens, and they will need to clear security again to re-enter.  Seating options have armrests, so bring something soft for sleeping on the cold floor if you want to stretch out. Here are sleep spots that travellers have reported:

• Pre-Security, Terminal 2’s far end, by the Sun Country check-in counters, is quiet.
• Head to the Baggage Claim area to grab the few available armrest-free circular sofas.

If you are a daytime napper, the areas on the airside are a little more comfortable, but overall seating remains limited and equipped with armrests. Common complaints are noisy overhead announcements and cleaning crews, so earplugs or noise-cancelling headphones are helpful.

For uninterrupted sleep, a few nearby hotels offer free shuttle service for guests. See our Airport Hotels section below for more info.

Security & Safety

Airport staff seem to tolerate overnight sleepers as long as they stay in the pre-security areas.

At the time of this update, we have no reports from travellers commenting on safety issues at San Diego Airport. However, sleeping in any airport can include a certain level of risk, especially when travelling alone. It’s important to take certain precautions to ensure your safety and the security of your valuables. Here are a few tips:

• Safety First. It’s a good idea to know where the security office is and look for video cameras where you plan to sleep. You can also ask the security personnel for advice on the safest places to spend the night.
• Don’t Seclude Yourself. If you’re travelling alone, we recommend you stay near other travellers or close to security. This will help you feel more secure and deter potential thieves.
• Hide Your Valuables. It’s also important to hide your valuables. Don’t leave them out in plain view, as this could make you a target for theft. Additionally, if you are a deep sleeper, you may want to padlock your bag to something or sleep with your bag up against a wall to make it harder for someone to access zippers and pockets. We have received reports of sleepers who woke up without their phones and laptop bags. The travellers were left with just their headphones and laptop bag strap.
• Stay Alert. It’s best to stay alert and awake if you feel unsafe or uncomfortable. Drink coffee or other caffeinated beverages to help you stay awake, and remember that you can always catch up on sleep during your flight. These simple precautions can help you enjoy a safe night at the airport.

Pro-tip: If you sleep in the public zone, don’t be surprised if you receive an early morning wake-up call. Security is known to make the rounds, waking people up as travellers arrive for morning flights.
