San Francisco International Airport (SFO) is a large airport with several terminals connected by walkways and AirTrain. The time taken to get through the airport depends on several factors, including the time of day, whether you have checked baggage, and whether you have TSA pre-check. Generally, it is recommended to arrive at the airport at least 90 minutes to 2 hours before a domestic flight and 2-3 hours before an international flight to allow sufficient time for check-in, baggage drop, security, and boarding. However, with TSA pre-check and no checked bags, some travellers report being able to get through the airport in under an hour. Additionally, the time taken to connect through SFO with customs can vary due to variables such as delays, lost baggage, immigration, and security.

What You'll Learn
Transit times for international flights
San Francisco International Airport (SFO) recommends that travellers arrive two hours before a domestic flight and three hours before an international flight. Individual airlines may have their own recommended arrival times, so it is worth checking with your airline before travelling.
SFO has six security checkpoints, one at each gate entrance. Only ticketed passengers are allowed beyond these checkpoints, and all 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.
Arriving international passengers connecting to onward flights must go through the federal inspection process and exit and re-enter security. This means that you will need to pick up your luggage, go through customs, and drop off your luggage again before your next flight. This process can take a significant amount of time, and some travellers have reported waiting in line for 2.5 hours. Therefore, it is recommended that you arrive at the airport early to ensure you have enough time to make your connection.
If you are connecting through SFO on an international flight, it is important to allow enough time for the connection. Some sources suggest that 1.5 hours may be enough time for a connection, but this may depend on the specific circumstances of your travel. If you are enrolled in the TSA PreCheck® program, you may be able to expedite the security screening process.
There are various transportation options for travelling to and from SFO and the city of San Francisco. The airport is located 15 miles from the city centre, and you can get there by car, train, subway, or bus. The journey time by train or subway is approximately 26 minutes, and tickets cost $8–11.

Customs and luggage collection
The time taken to get through customs and luggage collection at San Francisco International Airport (SFO) can vary due to several factors, including the time of day, flight arrival, and the number of agents available.
Firstly, passengers on international flights must complete US Customs and Border Protection (CBP) entry procedures in the Federal Inspection Area Arrivals Hall. After this, passengers proceed to the baggage reclaim area to collect their luggage. Waiting for luggage is often the most time-consuming part of the process. It can take anywhere from 10 minutes to over 2 hours, depending on various factors. For example, landing at 4 pm may result in a longer wait time due to potential lines and baggage wait times, whereas landing at 9 pm may be quicker, taking around 20 minutes.
After collecting luggage, passengers must go through customs. This process is usually quick, taking about 5 minutes, unless passengers have items to declare, which they should do for all plant and food items.
Passengers with connecting flights should proceed to the bag drop-off area, where they can drop off their luggage for their next flight without needing to check-in again. However, they will need to go through security again. It is recommended to allow at least 2 to 3 hours for the entire connection process, accounting for clearing immigration and customs, rechecking luggage, going through security, and reaching the domestic departure gate.
It is important to note that there is a possibility of unpredictable delays due to factors such as lost or delayed luggage, immigration, customs, getting lost between terminals, and other variables. Therefore, it is advisable to have a buffer and be prepared for potential delays when planning a trip involving San Francisco International Airport.
