Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1441, check with Delta Air Lines.
DL 1441 lands a B, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 279 flights, with a median arrival 10 minutes early.

These figures cover 279 flights between July 2025 and June 2026. Beyond the headline rate, 10.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When DL 1441 flies
DL 1441 flies DFW to DTW without a single fixed slot. Its most common scheduled departure was 17:00, used on 81 of 279 flights, with 18:41 (33 flights) and 18:07 (30 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 17:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 1441 runs 10 points better at 77.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
DL 1441 next to DFW to DTW

Across the year
DL 1441 quarter by quarter
DL 1441 did not run the same all year. Its best quarter was Jan–Mar 2026 at 86.1% on time and its weakest Jul–Sep 2025 at 68.4%, a swing of 18 points on roughly 70 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 1441 ranged from 73.2% on Sunday to 82.6% on Tuesday. With about 40 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 1441 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 5,135 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 51%Late-arriving aircraft
- 31%Carrier
- 12%National Airspace System
- 5%Extreme weather
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,135 reported delay minutes here, that single category outweighs weather by 10 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,135 delay minutes reported on DL 1441.
Cancellations sit at 1.43% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on three other city pairs in the data, including DFW to LGA (31), SLC to SMF (16) and TLH to ATL (6), 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. 279 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 77.8% on time with 1.43% cancelled over 279 flights. Those are rates from the past twelve months, not a forecast for any particular day.
