SkyWest on IND to AUS earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 454 flights, with a median arrival 9 minutes early.

Set against the rest of the country, SkyWest's IND to AUS record is 11 points better than the US average of 77.6%. That gap is worth roughly 106 fewer late arrivals for every thousand flights.

Every carrier on IND to AUS, 1,177 flights

These figures cover 454 flights between July 2025 and June 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

SkyWest against every carrier on IND to AUS

SkyWest flew 454 of the 1,177 flights on IND to AUS, about 39% of it. Its 88.2% on time is 5 points better than the route as a whole, which runs 83.4%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from SkyWest at 88.2% to Allegiant at 80.0%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When SkyWest runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 454 flights.

5am–8am361 flights89.4%
8am–11am1 flights—
11am–2pm72 flights84.7%

5pm–8pm20 flights—

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

The early departures do better, though not dramatically: 89.4% on time for the 5am–8am window against 84.7% for 11am–2pm. Worth taking if the schedule allows, not worth an extra connection. The 5am–8am window is the busiest, with 361 flights scheduled in it.

Across the year

SkyWest on IND to AUS through the year

Darker means more delays. Figures are on-time percentages.September best, December worst

December is the weak month at 64.5% on time, against 100.0% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. June was the busiest month here, with 74 flights.

Across the week, Saturday is the strongest day at 92.1% on time and Friday the weakest at 80.3%. 12 points is a smaller lever than departure hour, but it is free.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. Carrier accounts for 75% of the 4,390 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.

Carrier
75%
Extreme weather
17%
National Airspace System
8%

Extreme weather accounts for 17% 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 2.8 times the usual weather exposure. The split is drawn from 4,390 reported delay minutes.

The largest share of delay minutes, 75%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,280 of the 4,390 delay minutes reported here.

Cancellations are rare at 0.22%, 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.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.4% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 919 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg is a different operation and performs like one: it runs 79.4% on time across 454 flights, 9 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 9 points of difference.

One caution: this is a thin sample. 454 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking SkyWest on IND to AUS

Put together: treat all of this as provisional. 454 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 88.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 451 completed flights over 12 months sit behind that.
