The latest arrival of the period was on 28 July 2026, 16 hours 16 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 July 2026 | 16 hours 16 minutes | Carrier |
| 25 November 2025 | 14 hours 37 minutes | Carrier |
| 30 January 2026 | 5 hours 55 minutes | Late-arriving aircraft |

Delay causes
Why DL 2310 runs late
Late-arriving aircraft accounts for 60% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 60%Late-arriving aircraft
- 21%National Airspace System
- 18%Carrier
- 1%Extreme weather
60% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 60 to one. The split is drawn from 11,065 delay minutes reported on DL 2310.
Cancellations run at 4.17%, 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
22.3% 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 1,080 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 2310 is not only a RSW to LGA flight. It also flew LGA to RSW (288 flights, 62.2% 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. 288 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 2310
