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, and one even has shower facilities. See Airport Lounges in the guide below for locations and access information.

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 go back to landside until security reopens and will need to clear security again to re-enter. This is strictly enforced! Seating options have armrests, so bring along something soft for sleeping on the cold floor. Landside sleepers should head to the northwest corner of Terminal 2’s check-in area or the baggage claim area. Common complaints are noisy overhead announcements and cleaning crews, so earplugs or noise-cancelling headphones are useful. Explore our guide to sleeping in San Diego Airport or read some traveller reviews for more tips.  For uninterrupted sleep, a few nearby hotels offer free shuttle service for guests. See our Airport Hotels section below for more info.
