What You'll Learn
Domestic vs. international flight timings
For domestic flights, it is recommended that you arrive at the San Francisco airport at least two hours before your flight's departure time. This is to account for any potential delays and to ensure a smooth travel experience. Some sources suggest that even 1-1.5 hours is sufficient if you have TSA pre-check and no checked bags.
For international flights, it is generally advised to arrive at the airport three hours in advance. This is because international flights often involve additional procedures, such as customs and immigration checks, which can take longer. If you are connecting from a domestic flight to an international flight, you should still treat the domestic leg as a regular domestic flight in terms of check-in and arrival time. However, you should be prepared to show your passport during check-in and boarding for the international portion of your journey.
When booking flights, the recommended time frames differ between domestic and international travel. For domestic trips, it is generally advised to book within two weeks to two months of departure to find the best fares. In contrast, international travel often requires booking further in advance, typically more than 90 days in advance, to secure optimal pricing. However, it's important to note that the optimal booking window for international travel can vary depending on the specific route.

TSA PreCheck and other expedited screening options
San Francisco International Airport recommends that travellers arrive at the airport two hours before their domestic flight and three hours before their international flight. The Transportation Security Administration (TSA) offers a few options for expedited screening to reduce waiting times at security checkpoints.
TSA PreCheck
TSA PreCheck is an expedited screening option available at participating airports and airlines. It allows travellers to keep their shoes, belts, and light jackets on, and their electronics and 3-1-1 liquids in their bags during screening. The application process for TSA PreCheck can be completed online or at any enrollment location. Once approved, applicants receive a Known Traveler Number (KTN), which they can add to their airline reservations. About 99% of TSA PreCheck passengers wait less than 10 minutes. However, it's important to note that no individual is guaranteed expedited screening, and all travellers will be screened.
Global Entry
Global Entry is a U.S. Customs and Border Protection (CBP) program that provides expedited clearance for pre-approved, low-risk travellers upon arrival in the United States. It is available to U.S. citizens, U.S. lawful permanent residents, and citizens of partner countries enrolled in Global Entry, NEXUS, or SENTRI. Eligible travellers can enter their membership number when booking reservations or into their frequent flyer profile.
Mobile Passport
Mobile Passport is an option for eligible arriving guests, enabling them to submit their passport and customs declaration information via their iOS or Android device instead of filling out traditional paper forms. They can then proceed to the Mobile Passport Control express lane.
CLEAR
CLEAR is another option for expedited access to airport security lines in all terminals at San Francisco International Airport. It uses a biometric card for identification.

Early check-in options for early morning flights
San Francisco International Airport is open 24 hours a day, but only ticketed passengers are allowed in the airport between 6 pm and 8 am. The Transportation Security Administration (TSA) recommends arriving at the airport two hours before domestic flight departure and three hours before international flight departure. However, some sources suggest that 90 minutes is enough time to check in and pass through security for a domestic flight, and one hour if you have pre-check and no baggage to check in.
If you have an early morning flight and want to avoid the stress of a rushed check-in, there are several options available to you. Firstly, you could book a hotel near the airport and arrive the night before your flight, although this option can be expensive. Alternatively, you can book parking in advance through SFO's online booking system, which allows you to choose your parking dates and times. This option may be more affordable, but you will still need to factor in the time it takes to park your car and transport your luggage to the terminal.
Another option to expedite your check-in process is to use Mobile Passport. This service enables eligible arriving guests to submit their passport and customs declaration information via their iOS or Android device instead of filling out traditional paper forms. After submitting their information, passengers can proceed to the Mobile Passport Control express lane, reducing their overall check-in time.
CLEAR is another useful service that provides expedited access to airport security lines in all SFO terminals through a biometric card. You can visit clearme.com for more information on becoming a member and taking advantage of expedited security screening through participating airlines and airports.

Transit time considerations for connecting flights
When planning a trip involving connecting flights, it is essential to consider the time required for transit at the layover airport. San Francisco International Airport (SFO) provides various services and recommendations to facilitate seamless connections for passengers. Here are some key considerations for transit time when connecting flights at SFO:
Minimum Connection Time (MCT)
MCT refers to the minimum amount of time recommended by the airline for passengers to connect between flights. This time frame allows passengers to transfer between different terminals, go through security, and reach their next gate. At SFO, the recommended MCT is typically 2 to 3 hours for domestic and international connections. This longer connection time accounts for potential delays and the time needed to navigate a large airport.
Clearing Immigration and Customs
For international travellers connecting through SFO, clearing immigration and customs is a crucial step. The US Customs and Border Protection (CBP) procedures can take a significant amount of time, especially during peak travel hours. Passengers must exit the Arrivals Hall and proceed to the Federal Inspection Area for CBP processing. After completing the necessary procedures, they can then proceed to baggage claim and customs clearance.
Re-checking Luggage
Passengers connecting through SFO may need to pick up their checked luggage, go through customs, and then re-check their luggage before proceeding to their next flight. This process can vary depending on the traveller's origin and destination. It is important to allow sufficient time for this process, as it can involve standing in queues and navigating the airport with luggage.
Navigating Terminals and Security
SFO has multiple terminals that are connected by walkways and the AirTrain system. Passengers may need to transfer between terminals to reach their next gate. The time required for this transfer depends on the distance between terminals and the mode of transportation used. Additionally, passengers connecting through SFO may need to go through security again, depending on their origin and destination. The security checkpoints at SFO can experience varying wait times, so it is advisable to factor this into your connection time.
Allow for Potential Delays
When planning your connection, it is prudent to anticipate potential delays. Factors such as flight delays, lost or delayed luggage, long queues at immigration or customs, and navigating a large airport can impact your connection time. Allowing a buffer in your transit time helps ensure you don't miss your connecting flight due to unforeseen delays.
In conclusion, when planning a trip with connecting flights through San Francisco International Airport, it is essential to consider the various factors that can impact your transit time. By following the recommendations provided by the airport and allowing for potential delays, passengers can increase their chances of a smooth and timely connection to their final destination.
