Share of 334 completed flights by arrival against schedule.
14 of 107 late departures made up the time and arrived on time, 13% of them. In the other direction, 20 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 1414
The latest arrival of the period was on 6 August 2026, 4 hours 9 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across August, July, June and November, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 August 2026 | 4 hours 9 minutes | National Airspace System |
| 18 July 2026 | 4 hours 8 minutes | National Airspace System |

Delay causes
Why DL 1414 runs late
Late-arriving aircraft accounts for 48% of the 7,908 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 26%National Airspace System
- 25%Carrier
- 1%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,908 reported delay minutes here, that single category outweighs weather by 48 to one. The split is drawn from 7,908 delay minutes reported on DL 1414.
Cancellations run at 4.29%, 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
16.2% 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 1,069 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 350 flights under DL 1414 in the data flew JFK 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. 350 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 1414
For a booking, the cancellation rate is the figure to plan around on DL 1414: 4.29% of its 350 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.
