These figures cover 365 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Schedule
When DL 2041 flies

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 06:55 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2041 runs 17 points worse at 72.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 2041 quarter by quarter
DL 2041 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.8% on time and its weakest Jan–Mar 2026 at 57.6%, a swing of 30 points on roughly 73 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.

Scale runs 50% to 95%.
By weekday, DL 2041 ranged from 68.0% on Friday to 78.4% on Saturday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Arrival by arrival
How late DL 2041 runs when it is late
DL 2041 often beats the schedule: 96 of 357 completed flights, 27%, arrived 15 minutes or more early. Most of the lateness is short. 49 of the 97 late arrivals were under half an hour behind, and 19 reached an hour or more.

Share of 357 completed flights by arrival against schedule.
9 of 49 late departures made up the time and arrived on time, 18% of them. In the other direction, 57 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 SEA.
The worst days
Worst days for DL 2041
The latest arrival of the period was on 12 January 2026, 7 hours 13 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 January 2026 | 7 hours 13 minutes | Carrier |
| 7 December 2025 | 7 hours 9 minutes | Carrier |
| 10 January 2026 | 6 hours 17 minutes | Carrier |
| 31 March 2026 | 5 hours 45 minutes | Late-arriving aircraft |
| 18 April 2026 | 4 hours 21 minutes | Late-arriving aircraft |
Delay causes
Why DL 2041 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,387 reported delay minutes.
- 41%Carrier
- 35%National Airspace System
- 18%Late-arriving aircraft
- 6%Extreme weather
The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,185 of the 5,387 delay minutes reported here. The split is drawn from 5,387 delay minutes reported on DL 2041.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.82%.
Connections and routes
What a delay on this flight costs
5.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
At 1,721 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 365 flights under DL 2041 in the data flew ORD to SEA. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 365 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 2041
