These figures cover 552 flights between September 2025 and August 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.

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 552 flights.
- 5am–8am357 flights89.0%
- 8am–11am5 flights—
- 11am–2pm120 flights85.8%
- 2pm–5pm—
- 5pm–8pm70 flights82.9%
- 8pm–5am—
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 89.0% on time for the 5am–8am window against 82.9% for 5pm–8pm. Worth taking if the schedule allows, not worth an extra connection. The 5am–8am window is the busiest, with 357 flights scheduled in it.
Across the year
SkyWest on IND to AUS through the year
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. July was the busiest month here, with 85 flights.
Across the week, Wednesday is the strongest day at 93.4% on time and Monday the weakest at 76.7%, a spread of 17 points.

The worst days
Worst days for SkyWest on IND to AUS
The latest arrival of the period was on 14 August 2026, 7 hours 48 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.

|---|---|---|
| 14 August 2026 | 7 hours 48 minutes | Carrier |
| 25 January 2026 | 6 hours 28 minutes | Extreme weather |

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 80% of the 6,716 delay minutes carriers reported here, and the remaining four split what is left.
- 80%Carrier
- 14%Extreme weather
- 6%National Airspace System
Extreme weather accounts for 14% 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 2.3 times the usual weather exposure. The split is drawn from 6,716 reported delay minutes.
The largest share of delay minutes, 80%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,388 of the 6,716 delay minutes reported here.
Cancellations are rare at 0.18%, 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.
Connections and stage length
What a delay here costs
6.4% 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 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.
The return leg is a different operation and performs like one: it runs 80.9% on time across 552 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 552 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. 552 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 87.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 550 completed flights over 12 months sit behind that.
