A 09:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 873 runs 8 points worse at 75.9%. 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 873 quarter by 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.

Share of 320 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 43 departures that left 15 minutes late or more, only 1 made it up before arrival. In the other direction, 35 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 873
The latest arrival of the period was on 21 October 2025, 3 hours 25 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 October 2025 | 3 hours 25 minutes | Carrier |
| 18 October 2025 | 3 hours 24 minutes | Carrier |
| 4 July 2026 | 3 hours 21 minutes | Carrier |

Delay causes
Why DL 873 runs late
Carrier accounts for 64% of the 4,979 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Carrier
- 31%National Airspace System
- 4%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,192 of the 4,979 delay minutes reported here. The split is drawn from 4,979 delay minutes reported on DL 873.
Cancellations run at 6.10%, against 1.89% nationally. That is roughly one flight in fifteen cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
10.9% 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 1,389 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 one other city pair in the data, including DFW to LGA (222), but none flew often enough under DL 873 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to DFW only.
One caution: this is a thin sample. 344 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 873
For a booking, the cancellation rate is the figure to plan around on DL 873: 6.10% of its 344 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
