|---|---|---|---|---|---|
| B6384 | 50.9% | 3.11% | 13 min | 29.4% | 611 |

Why B6384 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies B6384 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, B6384 pushed back an average of 111 minutes late; when it came in on time or early, an average of 12 minutes late.
Matched by tail number to the aircraft’s previous flight into MCO: 524 of 592 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 | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| B6384 | 36% | 95% | 21% |
| Network, same turn | 17% | 69% | 9% |
64 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often B6384’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often B6384 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves MCO late, does that still matter by the time it reaches JFK?
B6384 pushes back an average of 54.4 minutes late and reaches the gate at JFK an average of 47.1 minutes late. The 7.3 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. It spends 23.0 minutes on the taxiways at MCO, 3.6 minutes longer than a typical MCO departure in the same hour.
On arrival at JFK, B6384 spends 8.9 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 2.6 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 35,508 MCO departures. Taxi-in is landing to gate, set against 360,684 arrivals at JFK. More on taxi time.

The hour it leaves MCO
B6384 has one departure time, 7:00 PM, so this is what that hour at MCO is worth.
On-time arrival rate. 35,508 departures from MCO are scheduled in the 7 PM–8 PM hour over the period, against 510,306 across the whole day.
B6384 is scheduled out of MCO at 7:00 PM, in the 7 PM–8 PM bank. Departures from MCO in that hour arrive on time 61.5% of the time against 74.6% across the airport’s whole day — the slot alone is worth 13.2 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from MCO, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
153 min late
against a median of 13 min late
B6384 has an average that understates its risk: a typical arrival is 13 min late, but the worst tenth are 140 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 611 records of B6384 operating MCO → 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.
