How DL707 performs
798 operations, March 2024 – July 2026.
DL707 arrived on time 72.0% of the time, against 79.8% for all JFK → LAX flights, so this departure is 7.8 percentage points worse than the route as a whole. Against Delta Air Lines’ own flights on this route it is 6.3 points worse.

Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| DL707 | 72.0% | 2.38% | -5 min | 10.2% | 798 |
| Delta Air Lines on JFK → LAX | 78.3% | 0.98% | -7 min | 7.4% | 10,287 |
| All JFK → LAX flights | 79.8% | 1.19% | -11 min | 7.6% | 31,151 |
DL707 has cancelled 2.38% of its scheduled departures (19 of 798), against 1.19% for all JFK → LAX flights — this specific departure cancels 1.2 percentage points more often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about DL707 specifically, not about the route it flies.

Why DL707 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies DL707 comes in late, and what that does to the departure.
The aircraft flying DL707 came in 15 or more minutes late on 19% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into JFK just before it, using the tail number in the DOT file, 266 of 781 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 |
|---|---|
| DL707 | 19% |
| Network, same turn | 23% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 90 minutes to 3 hours. How often DL707’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves JFK late, does that still matter by the time it reaches LAX?
DL707 pushes back an average of 20.7 minutes late and reaches the gate at LAX an average of 9.2 minutes late. The 11.5 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. It spends 37.0 minutes on the taxiways at JFK, 2.7 minutes longer than a typical JFK departure in the same hour.
On arrival at LAX, DL707 spends 15.9 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 5.2 minutes longer than a typical LAX arrival (10.7 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 LAX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 21,522 departures from JFK scheduled in the clock hour DL707 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LAX (595,170 flights), not just DL707’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. DL707 has one departure time, so this is what that time is worth.
On-time arrival rate. 21,522 departures from JFK are scheduled in the 7 PM–8 PM hour over the period, against 351,635 across the whole day.
DL707 is scheduled out of JFK at 7:00 PM, in the 7 PM–8 PM bank. Departures from JFK in that hour arrive on time 69.2% of the time against 77.0% across the airport’s whole day — the slot alone is worth 7.8 points worse 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.

Other routes DL707 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.

Because the same number has served different journeys, the statistics above describe only the route DL707 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
60 min late
against a median of 5 min early
DL707 has an average that understates its risk: a typical arrival is 5 min early, but the worst tenth are 65 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL707 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 798 records of DL707 operating JFK → LAX, 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.
