Historical statistics for January 2026, not live status or a forecast for this year’s January. For today’s conditions at AUS, see live FAA status.
AUS in January carries a cancellation problem, not just a delay problem: 4.7% of scheduled flights never operate, against 4.7% nationally. Of the ones that do fly, more than four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 6,707 flights, of which United Airlines flew 848 at 86.3% on time.
United Airlines is the most reliable of the five carriers covered here at 86.3% on time across 848 flights.

These figures cover 6,707 departures from Austin-Bergstrom International in January 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
January next to AUS's other months
Against AUS's own year, January ran 6 points better than the twelve-month rate of 76.6%, which makes it number two of twelve months, best first. Cancellations are where January stands out: 4.65% of scheduled departures were called off, 3.8 times the airport's rate across the year. Either side of it, December ran 77.9% on time and February 81.9%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window
The best time of day to leave AUS in January
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 17 points, against 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,257 flights90.5%
- 8am–11am1,082 flights87.9%
- 11am–2pm1,264 flights82.1%
- 2pm–5pm1,510 flights78.9%
- 5pm–8pm1,295 flights78.6%
- 8pm–5am299 flights73.2%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 90.5% of the time, against 73.2% for the overnight window. That is 17 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 1,510 flights scheduled in it.
Across the week, Wednesday is the strongest day at 86.8% on time and Sunday the weakest at 73.4%. 13 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at AUS in January
The choice of carrier is not cosmetic here. United Airlines arrives on time 86.3% of the time; American Airlines manages 75.2%. Sample sizes sit next to every figure, because a two-point gap across 836 flights means less than a ten-point one.

American Airlines cancels 8.6% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes
What held AUS up in January
One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 92,000 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.
- 43%Late-arriving aircraft
- 35%Carrier
- 14%National Airspace System
- 7%Extreme weather
- 0%Security
43% 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 92,000 reported delay minutes here, that single category outweighs weather by 6 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 92,000 reported delay minutes.
Cancellations run at 4.65%, against 4.71% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
7.1% of arrivals land an hour or more late, close to the national 7.6%. 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 an hour and a half, which a normal layover absorbs.
What to do with this
Flying from AUS in January
For a January trip through AUS: this is one of the better months to be flying from here, 82.8% on time with 4.65% cancelled. That is a base rate for the month as a whole; a single storm can still spoil a particular day.
