Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1041, check with Delta Air Lines.
DL 1041 lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about 45 minutes on average. That is a workable record, not a spotless one. That rests on 264 flights, with a median arrival 6 minutes early.
Set against the rest of the country, DL 1041's record is 5 points better than the US average of 77.6%. That gap is worth roughly 51 fewer late arrivals for every thousand flights.

These figures cover 264 flights between July 2025 and June 2026. The median arrival is 6 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.
Schedule
When DL 1041 flies
DL 1041 flies DTW to DFW without a single fixed slot. Its most common scheduled departure was 12:20, used on 73 of 264 flights, with 12:30 (41 flights) and 12:27 (33 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 12:20 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 1041 runs 4 points better at 82.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 1041 quarter by quarter
Quarter by quarter DL 1041 held fairly steady: 82.2% in Jul–Sep 2025, 85.1% in Oct–Dec 2025 and 79.5% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, DL 1041 did best on Wednesday at 91.9% on time and worst on Sunday at 75.0%. Each day rests on about 38 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1041 runs late
One category carries most of the weight here. Carrier accounts for 49% of the 1,946 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.
- 49%Carrier
- 38%National Airspace System
- 9%Late-arriving aircraft
- 4%Extreme weather
The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 954 of the 1,946 delay minutes reported here. The split is drawn from 1,946 delay minutes reported on DL 1041.
Cancellations sit at 1.89% against a national 1.81%, which is ordinary. Diversions add another 1.89%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.9% land an hour or more behind schedule, against 8.1% 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. 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 DTW (65), RDU to ATL (3) and ATL to RDU (3), 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. 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.
What to do with this
Booking DL 1041
