|---|---|---|
| 23 June 2026 | 4 hours 24 minutes | Late-arriving aircraft |
| 5 January 2026 | 4 hours 2 minutes | Carrier |

Delay causes
Why DL 1441 runs late
Late-arriving aircraft accounts for 50% of the 4,757 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 35%Carrier
- 15%National Airspace System
- 0%Extreme weather
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,757 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 4,757 delay minutes reported on DL 1441.
Cancellations sit at 1.40% against a national 1.89%, which is ordinary. Diversions add another 0.35%.
Connections and routes
What a delay on this flight costs
10.7% 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 986 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 DFW to LGA (31) and SLC to SMF (16), but none flew often enough under DL 1441 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to DTW only.
One caution: this is a thin sample. 285 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 1441
For a booking, read DL 1441 as 80.7% on time with 1.40% cancelled over 285 flights. Those are rates from the past twelve months, not a forecast for any particular day.
