These figures cover 334 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

A 11:10 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.3%, and DL 2396 runs 7 points worse at 71.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2396 quarter by quarter

DL 2396 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.3% on time and its weakest Oct–Dec 2025 at 62.0%, a swing of 21 points on roughly 84 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.

By weekday, DL 2396 did best on Tuesday at 76.1% on time and worst on Sunday at 60.0%. Each day rests on about 48 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late DL 2396 runs when it is late

DL 2396 often beats the schedule: 89 of 325 completed flights, 27%, arrived 15 minutes or more early. The 93 late arrivals split 36 under half an hour, 32 between 30 and 60 minutes, and 25 an hour or more.

Share of 325 completed flights by arrival against schedule.

22 of 74 late departures made up the time and arrived on time, 30% of them. In the other direction, 41 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at PBI.

The worst days

Worst days for DL 2396

The latest arrival of the period was on 14 May 2026, 7 hours 23 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.

Delay causes

Why DL 2396 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 5,300 reported delay minutes.

Carrier
39%
National Airspace System
38%
Late-arriving aircraft
22%

The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,088 of the 5,300 delay minutes reported here. The split is drawn from 5,300 delay minutes reported on DL 2396.

Cancellations run at 2.69%, against 1.89% nationally. That is about one flight in 40 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

7.7% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

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.

DL 2396 is not only a LGA to PBI flight. It also flew PBI to LGA (327 flights, 60.6% 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. 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 2396
