Share of 360 completed flights by arrival against schedule.
A late pushback is often recovered here: of 87 departures that left 15 minutes late or more, 28 still arrived on time. In the other direction, 23 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.

Connections and routes
What a delay on this flight costs
9.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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.
Every one of the 365 flights under DL 2749 in the data flew MSP to AUS. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 365 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 DL 2749
For a booking, read DL 2749 as 77.2% on time with 1.37% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
