American Airlines at Austin lands a B, level with the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That rests on 11,662 flights, of which Alaska Airlines flew 1,886 at 84.3% on time.
Measured against the airport rather than the country, American Airlines runs half a point ahead of the 76.5% 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.

Against the competition
Every carrier at AUS, ranked
The choice of carrier is not cosmetic here. Alaska Airlines arrives on time 84.3% of the time; Spirit Airlines manages 62.8%. Sample sizes sit next to every figure, because a two-point gap across 812 flights means less than a ten-point one.

Spirit Airlines cancels 6.5% 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 22 points between the best and worst carrier.
- 5am–8am3,495 flights88.1%
- 8am–11am1,495 flights81.3%
- 11am–2pm2,160 flights75.2%
- 2pm–5pm2,528 flights68.8%
- 5pm–8pm1,606 flights64.3%
- 8pm–5am378 flights69.0%
Scale runs 55% to 95%.
The 5pm–8pm window is where this operation falls apart: 64.3% on time, against 88.1% 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 3,495 flights scheduled in it.
Across the year
Seasonal pattern
Delays peak in March, when the on-time rate falls to 71.6%. February is the strongest month at 82.9%. Moving a flexible trip across that boundary buys 11 points. November was the busiest month here, with 1,084 flights.

48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 313,000 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 313,014 reported delay minutes.
Cancellations sit at 2.28% against a national 1.89%, which is ordinary. Diversions add another 0.17%.
10.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The sample behind these figures is 11,662 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: avoid the 5pm–8pm departure. It runs 64.3% on time against 88.1% for the 5am–8am slot, and that 24 points is the largest single thing you control here. Alaska Airlines is the strongest operator if the fares are close. 11,376 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 arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 23.3% of the 11,662 flights in this analysis, against 22.7% 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 84.3% on time across 1,886 flights. Spirit Airlines is at the other end on 62.8%, a gap of 22 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 88.1% on time. The 5pm–8pm window is the weakest at 64.3%, 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 March delays on American Airlines at AUS?
March is the weakest month at 71.6% on time, compared with 82.9% in February. Across the year that is 11 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
