These figures cover 334 flights between September 2025 and August 2026. The median arrival is 10 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2536 runs level with that at 89.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes
Why DL 2536 runs late
Carrier accounts for 73% of the 2,723 delay minutes carriers reported here, and the remaining four split what is left.
- 73%Carrier
- 26%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 73%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,977 of the 2,723 delay minutes reported here. The split is drawn from 2,723 delay minutes reported on DL 2536.
Cancellations run at 4.19%, 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 4.7% 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 1,035 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 PBI to LGA (248), but none flew often enough under DL 2536 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to PBI only.
One caution: this is a thin sample. 334 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 2536
For a booking, the cancellation rate is the figure to plan around on DL 2536: 4.19% of its 334 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
