DL 846 draws a D−. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 347 flights, with a median arrival 2 minutes late.
The national on-time rate over the same period is 77.3%, so DL 846 runs 14 points behind the country as a whole. Across a thousand flights that is about 136 extra late arrivals.

Across the year
DL 846 quarter by quarter
DL 846 did not run the same all year. Its best quarter was Jan–Mar 2026 at 73.4% on time and its weakest Oct–Dec 2025 at 41.3%, a swing of 32 points on roughly 87 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 846 did best on Saturday at 73.8% on time and worst on Thursday at 53.2%. Each day rests on about 50 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Share of 322 completed flights by arrival against schedule.
23 of 103 late departures made up the time and arrived on time, 22% of them. In the other direction, 37 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 846
The latest arrival of the period was on 19 May 2026, 8 hours 16 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across May, August, January, February and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 May 2026 | 8 hours 16 minutes | National Airspace System |
| 27 August 2026 | 7 hours 29 minutes | National Airspace System |

Delay causes
Why DL 846 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 8,234 reported delay minutes.
- 39%National Airspace System
- 36%Carrier
- 21%Late-arriving aircraft
- 4%Extreme weather
39% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 3,247 minutes out of 8,234, against a national NAS share of 21%. The split is drawn from 8,234 delay minutes reported on DL 846.
Cancellations run at 5.19%, against 1.89% nationally. That is about one flight in twenty 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
11.8% 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 three other city pairs in the data, including DFW to LGA (120), ATL to TLH (16) and TLH to ATL (16), but none flew often enough under DL 846 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. 347 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 846
For a booking, the cancellation rate is the figure to plan around on DL 846: 5.19% of its 347 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
