American Airlines at Austin lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrive 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 11,691 flights, of which Alaska Airlines flew 2,047 at 82.9% on time.
Measured against the airport rather than the country, American Airlines runs half a point behind the 76.6% weighted average across all carriers at AUS. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#6
Of 11 carriers clearing the floor at AUS
These figures cover 12,000 flights between July 2025 and June 2026. Beyond the headline rate, 10.8% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Against the competition
Every carrier at AUS, ranked
The choice of carrier is not cosmetic here. Alaska Airlines arrives on time 82.9% of the time; Spirit Airlines manages 63.2%. Sample sizes sit next to every figure, because a two-point gap across 994 flights means less than a ten-point one.

Spirit Airlines cancels 5.4% 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.
Route by route
Where American Airlines flies from AUS
American Airlines operates 8 routes out of AUS with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 20 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am3,430 flights87.6%
- 8am–11am1,567 flights81.6%
- 11am–2pm2,070 flights76.4%
- 2pm–5pm2,669 flights67.3%
- 5pm–8pm1,559 flights63.4%
- 8pm–5am396 flights66.7%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 63.4% on time, against 87.6% 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 3,430 flights scheduled in it.
Across the year
Seasonal pattern
July is the worst month at 70.7% on time, 12 points below February, the best at 82.9%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. November was the busiest month here, with 1,084 flights.
Delay causes
What holds this operation up

- 34%Carrier
- 13%National Airspace System

48% 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 312,000 reported delay minutes here, that single category outweighs weather by 10 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 312,383 reported delay minutes.
Cancellations run at 2.58%, against 1.81% nationally. That is about one flight in 40 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.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.8% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The sample behind these figures is 11,691 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
Put together: the calendar is the biggest lever here, not the carrier or the hour. February runs 82.9% on time and July 70.7%, a swing of 12 points. If the dates move at all, move them out of July before you think about anything else. 11,368 completed flights over 12 months sit behind that.
Common questions
American Airlines at AUS
How often is American Airlines at AUS delayed?
About one flight in four arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 23.8% of the 11,691 flights in this analysis, against 22.4% nationally. Delayed flights are late by close to two hours on average.
Which airline is most reliable on American Airlines at AUS?
Alaska Airlines leads at 82.9% on time across 2,047 flights. Spirit Airlines is at the other end on 63.2%, a gap of 20 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on American Airlines at AUS?
The 5am–8am departure window is the strongest at 87.6% on time. The 5pm–8pm window is the weakest at 63.4%, 24 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are July delays on American Airlines at AUS?
July is the weakest month at 70.7% on time, compared with 82.9% in February. Across the year that is 12 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
