These figures cover 280 flights between September 2025 and August 2026. The median arrival is 11 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

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:59 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 364 runs level with that at 91.1%. 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 364 quarter by quarter
DL 364 did not run the same all year. Its best quarter was Jul–Sep 2026 at 95.7% on time and its weakest Oct–Dec 2025 at 84.1%, a swing of 12 points on roughly 70 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 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 364 ranged from 90.0% on Tuesday to 94.0% 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.

The latest arrival of the period was on 19 December 2025, 1 hour 46 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 December 2025 | 1 hour 46 minutes | Carrier |
| 25 February 2026 | 1 hour 25 minutes | National Airspace System |
| 20 November 2025 | 1 hour 24 minutes | Carrier |

Delay causes
Why DL 364 runs late
Carrier accounts for 54% of the 1,109 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Carrier
- 45%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 54%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 594 of the 1,109 delay minutes reported here. The split is drawn from 1,109 delay minutes reported on DL 364.
Cancellations run at 3.93%, against 1.89% nationally. That is about one flight in 25 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 3.0% land an hour or more behind schedule, against 8.3% 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.
The same number turns up on two other city pairs in the data, including BZN to DTW (11) and DTW to BZN (11), 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. 280 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: 3.93% of its 280 scheduled flights did not operate. A late arrival costs roughly 45 minutes, but a cancellation costs the day, so leave a later option open.
