Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2165, check with Delta Air Lines.

DL 2165 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 364 flights, with a median arrival 10 minutes early.

Set against the rest of the country, DL 2165's record is 14 points better than the US average of 77.6%. That gap is worth roughly 141 fewer late arrivals for every thousand flights.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 10 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.

Schedule

When DL 2165 flies

DL 2165 flies FLL to JFK without a single fixed slot. Its most common scheduled departure was 07:00, used on 111 of 364 flights, with 07:12 (50 flights) and 07:25 (38 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 07:00 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 2 points better at 91.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 2165 next to FLL to JFK

Every carrier on FLL to JFK combined arrived on time 70.2% of the time across 3,877 flights, so DL 2165 is 22 points ahead of it. Delta flew 1,615 flights on the same city pair under all its flight numbers, including this one, and those ran 76.4% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 10 points.

Across the year

DL 2165 quarter by quarter

DL 2165 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.7% on time and its weakest Jan–Mar 2026 at 83.5%, a swing of 14 points on roughly 91 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.

Jan–Mar 202690 flights83.5%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2165 did best on Wednesday at 98.0% on time and worst on Monday at 82.0%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2165 runs late

One category carries most of the weight here. Carrier accounts for 50% of the 2,835 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.

Carrier
50%
Late-arriving aircraft
38%
National Airspace System
9%
Extreme weather
3%

38% 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 2,835 reported delay minutes here, that single category outweighs weather by 13 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 2,835 delay minutes reported on DL 2165.

Cancellations run at 3.85%, 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

Badly late arrivals are rare here: only 2.6% land an hour or more behind schedule, against 8.1% 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. 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 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: 3.85% 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.
