Across the year
DL 964 quarter by quarter
DL 964 did not run the same all year. Its best quarter was Jan–Mar 2026 at 84.3% on time and its weakest Oct–Dec 2025 at 55.8%, a swing of 29 points on roughly 82 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 45% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 964 did best on Tuesday at 75.5% on time and worst on Thursday at 62.5%. Each day rests on about 47 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Share of 313 completed flights by arrival against schedule.
31 of 111 late departures made up the time and arrived on time, 28% of them. In the other direction, 17 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 ATL.
The worst days
Worst days for DL 964
The latest arrival of the period was on 6 March 2026, 8 hours 37 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across March, May, August, October and November, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 8 hours 37 minutes | Carrier |
| 19 May 2026 | 4 hours 49 minutes | National Airspace System |
| 6 August 2026 | 4 hours 44 minutes | Late-arriving aircraft |
| 30 October 2025 | 4 hours 25 minutes | Late-arriving aircraft |
| 8 November 2025 | 4 hours 24 minutes | National Airspace System |
Delay causes
Why DL 964 runs late
Late-arriving aircraft accounts for 42% of the 7,295 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Late-arriving aircraft
- 31%National Airspace System
- 26%Carrier
- 1%Extreme weather
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,295 reported delay minutes here, that single category outweighs weather by 42 to one. The split is drawn from 7,295 delay minutes reported on DL 964.
Cancellations run at 4.57%, against 1.89% nationally. That is roughly 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
13.7% 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 762 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 DCA to ATL (16), but none flew often enough under DL 964 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to ATL only.
One caution: this is a thin sample. 328 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 964
For a booking, the cancellation rate is the figure to plan around on DL 964: 4.57% of its 328 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.
