Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2536, check with Delta Air Lines.
DL 2536 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 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 365 flights, with a median arrival 12 minutes early.
Set against the rest of the country, DL 2536's record is 14 points better than the US average of 77.6%. That gap is worth roughly 144 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 12 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 2536 flies
DL 2536 flies LGA to PBI without a single fixed slot. Its most common scheduled departure was 07:00, used on 167 of 365 flights, with 07:05 (108 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 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 3 points better at 92.0%. 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 2536 next to LGA to PBI

Across the year
DL 2536 quarter by quarter
Quarter by quarter DL 2536 held fairly steady: 93.2% in Jul–Sep 2025, 92.1% in Oct–Dec 2025, 92.9% in Jan–Mar 2026 and 89.7% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2536 ranged from 88.0% on Wednesday to 98.0% on Thursday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 2536 runs late
One category carries most of the weight here. Carrier accounts for 74% of the 2,153 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.
- 74%Carrier
- 24%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 74%, 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 1,601 of the 2,153 delay minutes reported here. The split is drawn from 2,153 delay minutes reported on DL 2536.
Cancellations run at 4.38%, against 1.81% nationally. That is roughly 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 3.2% 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 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. 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.
DL 2536 is not only a LGA to PBI flight. It also flew PBI to LGA (310 flights, 81.6% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 365 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: 4.38% of its 365 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.
