SkyWest Airlines at Austin lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrive 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 8,035 flights, of which Alaska Airlines flew 2,047 at 82.9% on time.
Measured against the airport rather than the country, SkyWest Airlines runs 4 points ahead of 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.

#3
Of 11 carriers clearing the floor at AUS
These figures cover 8,035 flights between July 2025 and June 2026. Beyond the headline rate, 8.8% 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 SkyWest Airlines flies from AUS
SkyWest Airlines operates 18 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 18 points, against 20 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,519 flights88.4%
- 8am–11am1,576 flights83.8%
- 11am–2pm511 flights80.2%
- 2pm–5pm2,249 flights79.2%
- 5pm–8pm1,237 flights70.4%
- 8pm–5am943 flights78.4%
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 88.4% of the time, against 70.4% for the evening window. That is 18 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 2,249 flights scheduled in it.
Across the year
Seasonal pattern
July is the worst month at 72.3% on time, 15 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. June was the busiest month here, with 832 flights.

Extreme weather accounts for 15% 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 2.4 times the usual weather exposure. The split is drawn from 133,458 reported delay minutes.
Cancellations are rare at 0.86%, below the national 1.81% 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.
8.8% of arrivals land an hour or more late, close to the national 8.1%. 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 are the an hour and a half kind, which a normal layover absorbs.
The sample behind these figures is 8,035 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. September runs 87.6% on time and July 72.3%, a swing of 15 points. If the dates move at all, move them out of July before you think about anything else. 7,930 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 arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 19.5% of the 8,035 flights in this analysis, against 22.4% 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 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 SkyWest Airlines at AUS?
The 5am–8am departure window is the strongest at 88.4% on time. The 5pm–8pm window is the weakest at 70.4%, 18 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 72.3% on time, compared with 87.6% in September. Across the year that is 15 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
