Historical statistics for November 2025, not live status or a forecast for this year’s November. For today’s conditions at SAT, see live FAA status.

SAT in November earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 5 points better than the national rate of 79.4%. When something does go wrong the average delay runs about an hour. That rests on 3,440 flights, of which Delta Air Lines flew 563 at 89.3% on time.

Delta Air Lines is the most reliable of the four carriers covered here at 89.3% on time across 563 flights.

SAT across all twelve months

These figures cover 3,440 departures from San Antonio International in November 2025. 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

November next to SAT's other months

Against SAT's own year, November ran 2 points better than the twelve-month rate of 81.8%, which makes it number four of twelve months, best first. Either side of it, October ran 83.7% on time and December 83.7%, so this month sits in line with its neighbours.

Departure window

The best time of day to leave SAT in November

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 31 points, against 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am1,020 flights93.3%
8am–11am414 flights86.8%
11am–2pm665 flights86.6%
2pm–5pm642 flights80.3%
5pm–8pm564 flights72.1%
8pm–5am135 flights62.4%

Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 62.4% on time, against 93.3% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 1,020 flights scheduled in it.

Across the week, Tuesday is the strongest day at 90.8% on time and Sunday the weakest at 77.1%. 14 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at SAT in November

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 89.3% of the time; American Airlines manages 78.4%. Sample sizes sit next to every figure, because a two-point gap across 653 flights means less than a ten-point one.

American Airlines	653	78.4%	80 min	1.99%	B

Delta leads American by 11 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held SAT up in November

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 36,000 reported delay minutes.

Late-arriving aircraft
40%
National Airspace System
32%
Carrier
25%
Extreme weather
2%
Security
0%

40% 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 36,000 reported delay minutes here, that single category outweighs weather by 18 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 36,106 reported delay minutes.

Cancellations sit at 1.19% against a national 2.49%, which is ordinary. Diversions add another 0.17%.

5.8% of arrivals land an hour or more late, close to the national 7.8%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
