Historical statistics for February 2026, not live status or a forecast for this year’s February. For today’s conditions at SAT, see live FAA status.

SAT in February earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 6 points better than the national rate of 80.2%. When something does go wrong the average delay runs about an hour. That rests on 2,671 flights, of which United Airlines flew 393 at 90.5% on time.

United Airlines is the most reliable of the four carriers covered here at 90.5% on time across 393 flights.

SAT across all twelve months

These figures cover 2,671 departures from San Antonio 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.

Against the year

February next to SAT's other months

Against SAT's own year, February ran 5 points better than the twelve-month rate of 81.8%, which makes it the best of the twelve months in the data. Either side of it, January ran 84.8% on time and March 79.9%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave SAT in February

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am765 flights94.2%
  • 8am–11am396 flights93.8%
  • 11am–2pm500 flights83.2%
  • 2pm–5pm530 flights79.5%
  • 5pm–8pm417 flights79.4%
  • 8pm–5am63 flights73.0%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 94.2% of the time, against 73.0% for the overnight window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 765 flights scheduled in it.

Across the week, Saturday is the strongest day at 90.8% on time and Wednesday the weakest at 85.0%. 6 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at SAT in February

The choice of carrier is not cosmetic here. United Airlines arrives on time 90.5% of the time; Southwest Airlines manages 84.5%. Sample sizes sit next to every figure, because a two-point gap across 915 flights means less than a ten-point one.

Delay causes

What held SAT up in February

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 24,000 reported delay minutes.

  • Carrier
    42%
  • Late-arriving aircraft
    41%
  • National Airspace System
    16%
  • Extreme weather
    2%

41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 24,000 reported delay minutes here, that single category outweighs weather by 26 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 24,219 reported delay minutes.

Cancellations sit at 1.27% against a national 2.25%, which is ordinary. Diversions add another 0.22%.

Badly late arrivals are rare here: only 3.8% land an hour or more behind schedule, against 6.5% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

What to do with this

Flying from SAT in February

For a February trip through SAT: this is one of the better months to be flying from here, 86.3% on time with 1.27% cancelled. That is a base rate for the month as a whole; a single storm can still spoil a particular day.
