SkyWest Airlines at Austin lands a B+, 4 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 8,430 flights, of which Alaska Airlines flew 1,886 at 84.3% on time.
Measured against the airport rather than the country, SkyWest Airlines runs 4 points 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 SkyWest Airlines flies from AUS
SkyWest Airlines operates 20 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 17 points, against 22 points between the best and worst carrier.
- 5am–8am1,625 flights88.6%
- 8am–11am1,665 flights84.3%
- 11am–2pm562 flights80.2%
- 2pm–5pm2,383 flights79.4%
- 5pm–8pm1,201 flights72.1%

Scale runs 65% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 88.6% of the time, against 72.1% for the evening 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 2,383 flights scheduled in it.
Across the year
Seasonal pattern
July is the worst month at 77.2% on time, 10 points below September, the best at 87.6%. 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. July was the busiest month here, with 932 flights.

Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 135,376 reported delay minutes.
Cancellations are rare at 0.87%, below the national 1.89% 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.
8.4% of arrivals land an hour or more late, close to the national 8.3%, so 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.
The sample behind these figures is 8,430 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 72.1% on time against 88.6% for the 5am–8am slot, and that 17 points is the largest single thing you control here. Alaska Airlines is the strongest operator if the fares are close. 8,318 completed flights over 12 months sit behind that.
Common questions
SkyWest Airlines at AUS
How often is SkyWest Airlines at AUS delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.1% of the 8,430 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
Which airline is most reliable on SkyWest 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 SkyWest Airlines at AUS?
The 5am–8am departure window is the strongest at 88.6% on time. The 5pm–8pm window is the weakest at 72.1%, 17 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 SkyWest Airlines at AUS?
July is the weakest month at 77.2% on time, compared with 87.6% in September. Across the year that is 10 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
