Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1419, check with Delta Air Lines.

DL 1419 sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 361 flights, with a median arrival 6 minutes early.

The national on-time rate over the same period is 77.6%, so DL 1419 runs 4 points behind the country as a whole. Across a thousand flights that is about 44 extra late arrivals.

These figures cover 361 flights between July 2025 and June 2026. Beyond the headline rate, 9.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When DL 1419 flies

DL 1419 flies JFK to FLL without a single fixed slot. Its most common scheduled departure was 15:20, used on 71 of 361 flights, with 14:55 (60 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 15:20 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1419 runs level with that at 73.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 1419 next to JFK to FLL

Every carrier on JFK to FLL combined arrived on time 72.7% of the time across 3,884 flights, so DL 1419 is about level with it. Delta flew 1,614 flights on the same city pair under all its flight numbers, including this one, and those ran 76.5% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 8 points.

Across the year

DL 1419 quarter by quarter

DL 1419 did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.1% on time and its weakest Oct–Dec 2025 at 63.6%, a swing of 17 points on roughly 90 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 1419 did best on Saturday at 85.1% on time and worst on Sunday at 61.2%. Each day rests on about 52 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1419 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 6,560 reported delay minutes.

National Airspace System
38%
Late-arriving aircraft
31%
Carrier
31%

38% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,492 minutes out of 6,560, against a national NAS share of 21%. The split is drawn from 6,560 delay minutes reported on DL 1419.

Cancellations sit at 2.49% against a national 1.81%, which is ordinary. Diversions add another 0.28%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. 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.

The same number turns up on one other city pair in the data, including FLL to JFK (162), but none flew often enough under DL 1419 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to FLL only.

One caution: this is a thin sample. 361 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 1419
