SFO across all twelve months

These figures cover 10,316 departures from San Francisco International in February 2026. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Departure window

The best time of day to leave SFO in February

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 17 points, against 20 points between the best and worst carrier.

5am–8am1,179 flights93.1%
8am–11am2,322 flights83.8%
11am–2pm2,109 flights76.3%
2pm–5pm1,560 flights77.2%
5pm–8pm1,360 flights78.5%
8pm–5am1,786 flights84.2%

Scale runs 70% to 100%.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 76.3% on time against 93.1% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8am–11am window is the busiest, with 2,322 flights scheduled in it.

Across the week, Friday is the strongest day at 88.6% on time and Wednesday the weakest at 77.6%, a spread of 11 points.

Carrier by carrier

Which airlines ran best at SFO in February

The choice of carrier is not cosmetic here. Alaska Airlines arrives on time 88.3% of the time; Southwest Airlines manages 68.6%. Sample sizes sit next to every figure, because a two-point gap across 684 flights means less than a ten-point one.

Delay causes

What held SFO up in February

Late-arriving aircraft accounts for 44% of the 142,000 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
44%
Carrier
34%
National Airspace System

Extreme weather

Security
0%

44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 142,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 142,155 reported delay minutes.

Cancellations sit at 1.21% against a national 2.25%, which is ordinary. Diversions add another 0.25%.

6.7% of arrivals land an hour or more late, close to the national 6.5%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
