What stands out
How B6884 compares to other flight numbers, not just to itself.
This flight's worst arrivals run unusually far past its typical one, a bigger gap than 97% of 11,788 comparable flight numbers.
A typical arrival is 9 min late, but the worst tenth run 114 minutes worse than that.

Why B6884 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
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
Share of the delay minutes US DOT attributed to each cause for B6884 on MCO → JFK. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies B6884 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, B6884 pushed back an average of 66 minutes late; when it came in on time or early, an average of 18 minutes late.
Each departure is matched to the flight the same aircraft flew into MCO just before it, using the tail number in the DOT file, 576 of 692 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 |
|---|---|---|---|
| B6884 | 37% | 74% | 30% |
| Network, same turn | 17% | 68% | 9% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often B6884’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often B6884 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?
B6884 pushes back an average of 41.4 minutes late and reaches the gate at JFK an average of 35.6 minutes late. The 5.8 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 22.7 minutes on the taxiways at MCO, 5.8 minutes longer than a typical MCO departure in the same hour.
On arrival at JFK, B6884 spends 9.8 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 1.6 minutes shorter than a typical JFK arrival (11.5 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 JFK. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 34,781 departures from MCO scheduled in the clock hour B6884 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at JFK (351,546 flights), not just B6884’s own. More on taxi time.

The hour it leaves MCO
Part of any flight’s record belongs to the clock rather than to the flight. B6884 has one departure time, so this is what that time is worth.
On-time arrival rate. 34,781 departures from MCO are scheduled in the 6 AM–7 AM hour over the period, against 498,221 across the whole day.
B6884 is scheduled out of MCO at 6:00 AM, in the 6 AM–7 AM bank. Departures from MCO in that hour arrive on time 92.2% of the time against 74.8% across the airport’s whole day — the slot alone is worth 17.4 points better before anything about this particular flight is considered.
The two airport figures cover every departure from MCO 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.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
123 min late
against a median of 9 min late
B6884 has an average that understates its risk: a typical arrival is 9 min late, but the worst tenth are 114 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. B6884 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 710 records of B6884 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 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.
