What You'll Learn

There are seven security checkpoints at SFO
San Francisco International Airport (SFO) has seven security checkpoints, each located at the entrance to the boarding areas of the gate areas. These checkpoints are for ticketed passengers only. All security checkpoints, except F3, have TSA PreCheck®, Priority Line, and Clear lanes. Passengers can enter through any checkpoint at any terminal, as long as they have a valid boarding pass for the same day of travel.
SFO is considered a safe airport, with no reports from travellers commenting on safety issues. However, there have been reports of homeless people wandering in the public areas of the terminals overnight. To ensure the safety and security of passengers and their belongings, Covenant Aviation Security (CAS), a private company under contract with the Transportation Security Administration (TSA), provides passenger and baggage screening at SFO. CAS treats all passengers and their belongings with courtesy, dignity, and respect during the security screening processes. Multiple cameras are installed at every passenger checkpoint location, capturing screening procedures and screener-customer interactions. These cameras are monitored by the TSA and SFO from state-of-the-art Operations Centres, ensuring the highest level of security and customer service.
To enhance security, SFO utilises new software that automatically detects potential threat items. This software eliminates passenger-specific images, instead indicating the location of potential threat items on a generic outline of a figure displayed on a monitor. Additionally, Transportation Security Officers (TSOs) may determine that an item not on the Prohibited Items List is prohibited to maintain traveller security. Passengers may also be subjected to additional screening to detect explosive threats.
SFO provides various amenities to make your time at the airport comfortable and convenient. The airport offers luggage storage, charging stations, and lounges with shower facilities. There are also nap rooms available for rent at FreshenUp, located inside the International Terminal. If you're looking for a place to stay, the Grand Hyatt is connected to the airport via the AirTrain, and there are other hotels and motels within a 15-minute taxi ride.
