Historical statistics for July 2025 to June 2026, not live status. For today’s DL 364, check with Delta Air Lines.

DL 364 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 50 minutes. That rests on 283 flights, with a median arrival 9 minutes early.

Set against the rest of the country, DL 364's record is 13 points better than the US average of 77.6%. That gap is worth roughly 129 fewer late arrivals for every thousand flights.

These figures cover 283 flights between July 2025 and June 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When DL 364 flies

DL 364 flies LGA to ATL without a single fixed slot. Its most common scheduled departure was 08:00, used on 141 of 283 flights, with 07:59 (138 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 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 364 runs 6 points better at 90.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 364 next to LGA to ATL

Delta flew 4,933 flights on the same city pair under all its flight numbers, including this one, and those ran 79.9% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 9 points.

Across the year

DL 364 quarter by quarter

DL 364 did not run the same all year. Its best quarter was Jan–Mar 2026 at 94.8% on time and its weakest Oct–Dec 2025 at 84.1%, a swing of 11 points on roughly 71 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 202666 flights94.8%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 364 ranged from 89.8% on Monday to 94.1% on Wednesday. With about 40 flights behind each day, a spread of 4 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 364 runs late

One category carries most of the weight here. Carrier accounts for 59% of the 1,281 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

59%
National Airspace System
33%
Late-arriving aircraft
7%
Extreme weather
1%

The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 759 of the 1,281 delay minutes reported here. The split is drawn from 1,281 delay minutes reported on DL 364.

Cancellations run at 3.53%, 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

Badly late arrivals are rare here: only 3.7% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

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 two other city pairs in the data, including BZN to DTW (3) and DTW to BZN (3), but none flew often enough under DL 364 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. 283 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 364

For a booking, the cancellation rate is the figure to plan around on DL 364: 3.53% of its 283 scheduled flights did not operate. A late arrival costs about 50 minutes, but a cancellation costs the day, so leave a later option open.
