Historical statistics for July 2025 to June 2026, not live status. For today’s DL 964, check with Delta Air Lines.

DL 964 sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 8 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 325 flights, with a median arrival 8 minutes early.

The national on-time rate over the same period is 77.6%, so DL 964 runs 8 points behind the country as a whole. Across a thousand flights that is about 80 extra late arrivals.

These figures cover 325 flights between July 2025 and June 2026. Beyond the headline rate, 13.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When DL 964 flies

DL 964 flies LGA to ATL without a single fixed slot. Its most common scheduled departure was 18:00, used on 239 of 325 flights, with 18:30 (75 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 18:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 964 runs level with that at 69.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 964 next to LGA to ATL

Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 12 points.

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 81 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.

Jan–Mar 202674 flights84.3%

Scale runs 45% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 964 did best on Tuesday at 76.0% on time and worst on Sunday at 60.0%. Each day rests on about 46 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 964 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 6,975 reported delay minutes.

National Airspace System
36%
Late-arriving aircraft
34%
Carrier
30%
Extreme weather
1%

36% 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 2,481 minutes out of 6,975, against a national NAS share of 21%. The split is drawn from 6,975 delay minutes reported on DL 964.

Cancellations run at 3.38%, against 1.81% nationally. That is about one flight in 30 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. 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 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. 325 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: 3.38% of its 325 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.
