These figures cover 259 flights between September 2025 and August 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Across the year
DL 1041 quarter by quarter
DL 1041 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.0% on time and its weakest Apr–Jun 2026 at 79.5%, a swing of 11 points on roughly 65 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.
- Jul–Sep 202530 flights90.0%
- Oct–Dec 202592 flights85.1%
- Jan–Mar 20264 flights—
- Apr–Jun 202676 flights79.5%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1041 did best on Wednesday at 91.9% on time and worst on Sunday at 73.0%. Each day rests on about 37 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 1041 runs when it is late

Share of 250 completed flights by arrival against schedule.
3 of 23 late departures made up the time and arrived on time, 13% of them. In the other direction, 19 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 DFW.
The worst days
Worst days for DL 1041
The latest arrival of the period was on 16 July 2026, 2 hours 30 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.

|---|---|---|
| 16 July 2026 | 2 hours 30 minutes | Carrier |

Delay causes
Why DL 1041 runs late
Carrier accounts for 49% of the 1,887 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 37%National Airspace System
- 10%Late-arriving aircraft
- 3%Extreme weather
The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 921 of the 1,887 delay minutes reported here. The split is drawn from 1,887 delay minutes reported on DL 1041.
Cancellations sit at 1.93% against a national 1.89%, which is ordinary. Diversions add another 1.54%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.0% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 three other city pairs in the data, including DFW to DTW (65), RDU to ATL (7) and ATL to RDU (7), but none flew often enough under DL 1041 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to DFW only.
One caution: this is a thin sample. 259 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 1041
For a booking, read DL 1041 as 84.4% on time with 1.93% cancelled over 259 flights. Those are rates from the past twelve months, not a forecast for any particular day.
