DL1422
New York (JFK) to Fort Lauderdale (FLL) · scheduled 7:00 AM – 10:45 AM
How DL1422 performs
905 operations, January 2024 – July 2026.
DL1422 arrived on time 89.6% of the time, against 72.5% for all JFK → FLL flights, so this departure is 17.1 percentage points better than the route as a whole. Against Delta Air Lines’ own flights on this route it is 12.0 points better.
DL1422’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 7:30 AM earlier on, and around 7:00 AM more recently — a 30-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

Why DL1422 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
the inbound aircraft was late, so this flight started late

Does a late aircraft delay this flight?
How often the plane that flies DL1422 comes in late, and what that does to the departure.
DL1422 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.7 hours on the ground at JFK, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, DL1422 pushed back an average of 2 minutes late; when it came in on time or early, an average of 0 minutes late.
Each departure is matched to the flight the same aircraft flew into JFK just before it, using the tail number in the DOT file, 755 of 883 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| DL1422 | 35% | 8% | 6% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often DL1422’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often DL1422 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves JFK late, does that still matter by the time it reaches FLL?
DL1422 pushes back an average of 0.9 minutes late and reaches the gate at FLL an average of 7.2 minutes early. The 8.1 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. Its 25.2 minutes on the taxiways at JFK is about what any departure from the airport in that hour spends.
On arrival at FLL, DL1422 spends 6.2 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is 1.2 minutes shorter than a typical FLL arrival (7.4 min).
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached FLL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 28,461 departures from JFK scheduled in the clock hour DL1422 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at FLL (278,720 flights), not just DL1422’s own. More on taxi time.

The hour it leaves JFK
Part of any flight’s record belongs to the clock rather than to the flight. DL1422 has one departure time, so this is what that time is worth.
On-time arrival rate. 28,461 departures from JFK are scheduled in the 7 AM–8 AM hour over the period, against 351,635 across the whole day.
DL1422 is scheduled out of JFK at 7:00 AM, in the 7 AM–8 AM bank. Departures from JFK in that hour arrive on time 85.9% of the time against 77.0% across the airport’s whole day — the slot alone is worth 8.9 points better before anything about this particular flight is considered.
The two airport figures cover every departure from JFK to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

By day of week
Does DL1422 run worse on particular days?
Tuesday is historically the most reliable day and Sunday the least, a gap of 7.1 percentage points.

Because the same number has served different journeys, the statistics above describe only the route DL1422 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL1422 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 905 records of DL1422 operating JFK → FLL, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
