    SFO Airport Security Checkpoints - Location and Hours

    There are a total of 7 security checkpoints at SFO.  CLEAR is now available in Terminal 1, 2, 3 and International checkpoints.

There are some exceptions to this where passengers can connect to certain terminals without exiting and re-entering security, for example, you can clear security at Terminal 1, checkpoint C, gates 40-48 and walk to Terminal 2, checkpoint D, gates 50-59.  The Terminals and departure gates are shown below.

    SFO TSA wait times can be cut down considerably if you participate in the TSA Pre program. You can even sign up for TSA PreCheck before your next SFO flight - there’s an enrollment center in the San Francisco International Terminal (G side, pre-security, near the BART station). According to the TSA, the enrollment center is open from 7:30 AM - 11:30AM and 12:00PM-4:00PM M-F.

    About SFO Security Wait Times 

    Security wait times at San Francisco SFO Airport are approximate and can vary based on several factors including severe weather, TSA staffing, airport construction, etc.

    SFO TSA wait time forecasts are made leveraging flight volume data and TSA staffing models. Using advanced data science, wait times for San Francisco SFO Airport are projected, that barring extreme outliers, are within five minutes in accuracy, as validated by large US airlines. The TSA urges all travelers to arrive at the airport well in advance of scheduled flight departures and has provided security checkpoint wait time information as a guide to assist in travel planning. Please be sure to check with your airline for ticket counter wait times as well as possible changes to flight schedules, as these and other factors influence your decision regarding how early to arrive at SFO. Please be aware that each airline has a recommended arrival time and even stricter required arrival times.

    All airlines require that you arrive at the check-in counter, the flight's departure gate and even onboard and in your assigned seat a prescribed amount of time before the flight's scheduled departure time. The amount of the advance arrival time required varies depending on the airline you are using. Most airlines' conditions of carriage state that with many of their tickets, failure to arrive at the check-in counter, the flight's departure gate and your assigned seat a prescribed amount of time before the flight's scheduled departure time may cause you to be denied boarding and cause you to forfeit any refund or other compensation due for the unused ticket even if you have advance seat assignments and advance boarding passes.
