AUS in October lands a B+, 3 points worse than the national rate of 79.7%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 7,845 flights, of which SkyWest Airlines flew 638 at 83.7% on time.

SkyWest Airlines is the most reliable of the five carriers covered here at 83.7% on time across 638 flights.

AUS across all twelve months

These figures cover 7,845 departures from Austin-Bergstrom International in October 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

October next to AUS's other months

Against AUS's own year, October ran level with the twelve-month rate of 76.6%, which makes it number seven of twelve months, best first. Cancellations were unusually low for AUS in October, at 0.40% against 1.21% across the year. Either side of it, September ran 84.2% on time and November 76.0%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window

The best time of day to leave AUS in October

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 27 points, against 10 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am1,464 flights92.2%
8am–11am1,169 flights88.1%
11am–2pm1,380 flights76.5%
2pm–5pm1,713 flights69.8%
5pm–8pm1,395 flights65.3%
8pm–5am724 flights66.7%

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

Book the early departure. Flights leaving between 5am–8am arrive on time 92.2% of the time, against 65.3% for the evening window. That is 27 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 1,713 flights scheduled in it.

Across the week, Wednesday is the strongest day at 86.2% on time and Sunday the weakest at 68.6%. 18 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at AUS in October

The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 83.7% of the time; Southwest Airlines manages 74.2%. Sample sizes sit next to every figure, because a two-point gap across 3,448 flights means less than a ten-point one.

SkyWest leads Southwest by 10 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held AUS up in October

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 111,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

45% 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 111,000 reported delay minutes here, that single category outweighs weather by 36 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 111,274 reported delay minutes.

Cancellations are rare at 0.40%, below the national 0.53% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

6.8% of arrivals land an hour or more late, close to the national 6.3%. 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.
