Complete Guide to Airport Timing
San Francisco International Airport (SFO) serves as the Bay Area's primary international gateway. SFO is known for efficient security compared to other major airports.
How Early Should I Arrive at SFO for a Domestic Flight?
Arrive 2 hours before departure for domestic flights. SFO's security is generally efficient, but you still need time for parking, check-in, security, and reaching your gate. During peak hours or if checking bags, this buffer is essential.
How Early Should I Arrive at SFO for an International Flight?
Arrive 3 hours before departure for international flights. The International Terminal (Terminal A) handles all international flights and can be busy during peak travel times. Allow extra time for international check-in procedures.
When is SFO Most Busy?
SFO's busiest periods are 6am-9am and 4pm-7pm. Security lines average 20-30 minutes during these times. Off-peak hours typically have much shorter waits, often under 15 minutes.
How Much Time Should I Allow for Bay Area Traffic to SFO?
US-101 and I-280 experience heavy congestion during commute hours. From San Francisco, allow 45-60 minutes during rush hour, though the trip can be as short as 20-25 minutes during off-peak times. Use our calculator above for real-time traffic estimates based on your location.
Which SFO Terminal Should I Go To?
SFO has 4 terminals: Terminal 1 (Southwest), Terminal 2 (American, Virgin America), Terminal 3 (United), and International Terminal/Terminal A (all international flights). Check your airline before leaving. All terminals are connected post-security via AirTrain.

Frequently Asked Questions
What are current SFO wait times?
SFO security wait times typically range from 10-45 minutes depending on time of day. Early morning (5-7 AM) and late evening (8 PM+) have the shortest waits at 10-15 minutes. Peak times (7-9 AM and 3-6 PM) can see waits of 30-45 minutes or longer. Use our calculator above for real-time wait times from your exact location, factoring in current traffic and TSA security lines.
How early should I arrive at SFO for a domestic flight?
Arrive 2 hours before your domestic flight departure. This allows time for parking or BART arrival (10-15 minutes), check-in and bag drop if needed (10-15 minutes), security screening (15-30 minutes depending on time of day), and walking to your gate (5-10 minutes). SFO's security is generally more efficient than LAX or other major airports. If you have TSA PreCheck and only carry-on luggage during off-peak hours (10am-3pm), 90 minutes might work, but 2 hours is safer.
How long does security take at SFO?
Average security wait time is 15-25 minutes, making SFO one of the more efficient major California airports. During peak hours (6-9am and 4-7pm), expect waits of 20-30 minutes. Off-peak hours typically see waits under 15 minutes. TSA PreCheck can save you 10-15 minutes. The International Terminal tends to have slightly longer lines than domestic terminals. Check the MyTSA app for current wait times at your specific terminal before you leave.
Can I take BART to SFO?
Yes! BART (Bay Area Rapid Transit) provides direct service to SFO's International Terminal, with free AirTrain connections to all other terminals. BART is often faster than driving during rush hour, especially from San Francisco (30 minutes) and East Bay. Trains run every 15-20 minutes. This is a reliable, stress-free alternative to dealing with US-101 or I-280 traffic and airport parking.
Which SFO terminal should I go to?
Check your airline before leaving: Terminal 1 serves Southwest; Terminal 2 serves American, Virgin America, and Alaska Airlines; Terminal 3 serves United; International Terminal (Terminal A) handles all international flights. If you need to transfer between terminals, use the free AirTrain which connects all terminals and runs 24/7. Allow 5-10 minutes for inter-terminal transfers.
