These figures cover 364 flights between September 2025 and August 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:25 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2165 runs level with that at 89.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 25 September 2025 | 14 hours 7 minutes | Late-arriving aircraft |
| 7 September 2025 | 7 hours 56 minutes | Late-arriving aircraft |

Delay causes
Why DL 2165 runs late
Carrier accounts for 56% of the 3,702 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 29%Late-arriving aircraft
- 12%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,078 of the 3,702 delay minutes reported here. The split is drawn from 3,702 delay minutes reported on DL 2165.
Cancellations run at 2.75%, against 1.89% nationally. That is roughly 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
Badly late arrivals are rare here: only 4.2% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 364 flights under DL 2165 in the data flew FLL to JFK. 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. 364 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 2165
For a booking, the cancellation rate is the figure to plan around on DL 2165: 2.75% of its 364 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.
