Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Delta Air Lines.
Delta on MSP to AUS lands a B+, about a point 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 about an hour on average. That rests on 1,023 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Delta on MSP to AUS from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Delta against every carrier on MSP to AUS
Delta flew 1,023 of the 1,685 flights on MSP to AUS, most of the route. Its 78.7% on time is about level with the route as a whole at 80.0%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from SkyWest at 85.4% to Southwest at 78.6%. Two 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 Delta 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 1,023 flights.
- 5am–8am1 flights—
- 8am–11am338 flights81.8%
- 11am–2pm30 flights76.7%
- 2pm–5pm288 flights77.0%
- 5pm–8pm165 flights74.8%
- 8pm–5am201 flights79.3%
Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 81.8% on time for the 8am–11am window against 74.8% for 5pm–8pm. Worth taking if the schedule allows, not worth an extra connection. The 8am–11am window is the busiest, with 338 flights scheduled in it.
Across the year
Delta on MSP to AUS through the year
July is the worst month at 64.7% on time, 24 points below February, the best at 88.5%.

January was the busiest month here, with 90 flights.
Across the week, Wednesday is the strongest day at 86.7% on time and Saturday the weakest at 72.3%, a spread of 14 points.

Share of 1,014 completed flights by arrival against schedule.
54 of 219 late departures made up the time and arrived on time, 25% of them. In the other direction, 51 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at AUS.
The worst days
Worst days for Delta on MSP to AUS
The latest arrival of the period was on 17 May 2026, 4 hours 3 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 May 2026 | 4 hours 3 minutes | Carrier |
| 7 August 2026 | 3 hours 36 minutes | Carrier |
| 13 July 2026 | 3 hours 29 minutes | Late-arriving aircraft |
| 16 June 2026 | 3 hours 27 minutes | Late-arriving aircraft |
| 19 January 2026 | 3 hours 11 minutes | Carrier |
Delay causes
Why Delta runs late on this route
Carrier accounts for 54% of the 12,000 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Carrier
- 24%National Airspace System
- 20%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 54%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 6,779 of the 12,000 delay minutes reported here. The split is drawn from 12,476 reported delay minutes.
Cancellations are rare at 0.88%, 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
8.5% 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 about an hour, which a normal layover absorbs.
The 1,042 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 runs 79.6% on time across 1,022 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 1,023 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 Delta on MSP to AUS
Put together: treat all of this as provisional. 1,023 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 78.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 1,014 completed flights over 12 months sit behind that.
