The worst days
Worst days for DL 1042
The latest arrival of the period was on 19 January 2026, 16 hours 46 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.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 January 2026 | 16 hours 46 minutes | Carrier |
| 20 November 2025 | 3 hours 34 minutes | Carrier |
| 7 August 2026 | 3 hours 18 minutes | Late-arriving aircraft |
| 27 December 2025 | 2 hours 55 minutes | Carrier |

Delay causes
Why DL 1042 runs late
Late-arriving aircraft accounts for 48% of the 5,839 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 37%Carrier
- 12%National Airspace System
- 3%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,839 reported delay minutes here, that single category outweighs weather by 15 to one. The split is drawn from 5,839 delay minutes reported on DL 1042.
Cancellations are rare at 0.38%, 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 routes
What a delay on this flight costs
11.1% 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.
The same number turns up on two other city pairs in the data, including MSP to AUS (163) and PVD to ATL (28), but none flew often enough under DL 1042 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to AUS to MSP only.
One caution: this is a thin sample. 264 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.
