Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2308, check with Delta Air Lines.

DL 2308 draws a D−. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is an hour and a half behind schedule. Build slack into anything you connect to. That rests on 322 flights, with a median arrival 2 minutes late.

The national on-time rate over the same period is 77.6%, so DL 2308 runs 15 points behind the country as a whole. Across a thousand flights that is about 153 extra late arrivals.

These figures cover 322 flights between July 2025 and June 2026. Beyond the headline rate, 20.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When DL 2308 flies

DL 2308 flies LGA to FLL without a single fixed slot. Its most common scheduled departure was 19:20, used on 88 of 322 flights, with 19:59 (56 flights) and 19:29 (52 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 19:20 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2308 runs 6 points worse at 62.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

DL 2308 quarter by quarter

DL 2308 did not run the same all year. Its best quarter was Apr–Jun 2026 at 69.7% on time and its weakest Oct–Dec 2025 at 52.1%, a swing of 18 points on roughly 81 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.

Oct–Dec 202577 flights52.1%
Jan–Mar 202679 flights68.9%

Scale runs 45% to 75%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2308 ranged from 58.3% on Sunday to 70.2% on Friday. With about 46 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2308 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 9,920 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.

47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 9,920 reported delay minutes here, that single category outweighs weather by 47 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 9,920 delay minutes reported on DL 2308.

Cancellations run at 4.04%, against 1.81% 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 20.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 1,076 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.

Every one of the 322 flights under DL 2308 in the data flew LGA to FLL. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 322 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 2308

For a booking, the cancellation rate is the figure to plan around on DL 2308: 4.04% of its 322 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.
