San Francisco Airport Overview

San Francisco Airport (SFO) has four terminals—Terminal 1 (Boarding Area B), Terminal 2 (Boarding Area D), Terminal 3 (Boarding Areas E and F), and the International Terminal (Areas A and G). Terminals are interconnected via walkways and the complimentary AirTrain, connecting to parking and BART transit. Highlights include diverse eateries, complimentary Wi-Fi, and showers in the International Terminal. Economy passengers can purchase lounge access for added comfort.

Sleeping in San Francisco Airport

Weather delays are frequent at SFO, making seats highly coveted during long layovers or overnight stays. Seating comfort varies, with padded seating primarily found in the International Terminal's airside areas. Armrest-free seats are limited, but travelers can find quiet corners to rest on floors, some carpeted. Travel Code recommends packing a travel mat, sleeping bag, blanket, eye mask, and earplugs to counteract bright lighting, noise, and cool temperatures.

San Francisco Airport staff generally tolerates overnight guests; however, security checkpoints for ID and boarding passes are common overnight. For better rest, travelers can book the on-site nap rooms at Freshen Up (fee-based hourly rooms available), or opt for a comfortable stay at nearby airport hotels offering free shuttle service.
