Why DL650 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
Share of the delay minutes US DOT attributed to each cause for DL650 on HNL → JFK. Only delays of 15 minutes or more are attributed. What the five causes mean

Does a late aircraft delay this flight?
How often the plane that flies DL650 comes in late, and what that does to the departure.
The aircraft flying DL650 came in 15 or more minutes late on 18% 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.
Matched by tail number to the aircraft’s previous flight into HNL: 580 of 597 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| DL650 | 18% |
| Network, same turn | 23% |
A long gap on the ground 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 DL650’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 HNL late, does that still matter by the time it reaches JFK?
DL650 pushes back an average of 4.7 minutes late and reaches the gate at JFK an average of 9.1 minutes early. The 13.8 minutes between those two figures are slack the published schedule already carries, so on average a late pushback on this flight is made up before the gate. It spends 19.5 minutes on the taxiways at HNL, 2.8 minutes longer than a typical HNL departure in the same hour.
On arrival at JFK, DL650 spends 10.5 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 1.0 minutes shorter than a typical JFK arrival (11.5 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 14,446 HNL departures. Taxi-in is landing to gate, set against 360,684 arrivals at JFK. More on taxi time.

The hour it leaves HNL
DL650 has one departure time, 3:50 PM, so this is what that hour at HNL is worth.
On-time arrival rate. 14,446 departures from HNL are scheduled in the 3 PM–4 PM hour over the period, against 191,167 across the whole day.
DL650 is scheduled out of HNL at 3:50 PM, in the 3 PM–4 PM bank. Departures from HNL in that hour arrive on time 78.3% of the time against 85.2% across the airport’s whole day — the slot alone is worth 6.9 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from HNL, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

Calculated by FlyerIntel from 606 records of DL650 operating HNL → JFK, 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 reported separately, not in the on-time rate.
