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 79 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 2308 did best on Friday at 74.5% on time and worst on Monday at 51.0%. Each day rests on about 45 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Share of 296 completed flights by arrival against schedule.
21 of 109 late departures made up the time and arrived on time, 19% of them. In the other direction, 21 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 FLL.
The worst days
Worst days for DL 2308
The latest arrival of the period was on 6 September 2025, 14 hours 1 minute 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.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 September 2025 | 14 hours 1 minute | Carrier |
| 27 August 2026 | 6 hours 56 minutes | Late-arriving aircraft |
| 10 August 2026 | 4 hours 49 minutes | Carrier |
| 18 January 2026 | 4 hours | Carrier |
| 9 November 2025 | 3 hours 46 minutes | Late-arriving aircraft |
Delay causes
Why DL 2308 runs late
Late-arriving aircraft accounts for 50% of the 9,617 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 30%Carrier
- 19%National Airspace System
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,617 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 9,617 delay minutes reported on DL 2308.
Cancellations run at 5.41%, against 1.89% nationally. That is about one flight in twenty 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
19.6% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
Every one of the 314 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. 314 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: 5.41% of its 314 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.
