How B685 performs
1,122 operations, July 2023 – July 2026.
B685 arrived on time 84.7% of the time, against 78.8% for all BUF → MCO flights, so this departure is 5.9 percentage points better than the route as a whole. Against JetBlue’s own flights on this route it is 4.1 points better.

Why B685 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
Share of the delay minutes US DOT attributed to each cause for B685 on BUF → MCO. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies B685 comes in late, and what that does to the departure.
B685 is usually the aircraft’s first flight of the day: the schedule gives it a median of 7.2 hours on the ground at BUF, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, B685 pushed back an average of 10 minutes late; when it came in on time or early, an average of 3 minutes early.
Each departure is matched to the flight the same aircraft flew into BUF just before it, using the tail number in the DOT file, 937 of 1,106 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 |
|---|---|---|---|
| B685 | 32% | 18% | 5% |
| 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 B685’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often B685 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves BUF late, does that still matter by the time it reaches MCO?
B685 pushes back an average of 4.5 minutes late and reaches the gate at MCO an average of 0.3 minutes late. The 4.2 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 15.5 minutes on the taxiways at BUF, 1.0 minutes shorter than a typical BUF departure in the same hour.
On arrival at MCO, B685 spends 10.4 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 about what any arrival at MCO spends on the ground before reaching the gate.
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 MCO. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 10,894 departures from BUF scheduled in the clock hour B685 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at MCO (498,229 flights), not just B685’s own. More on taxi time.

The hour it leaves BUF
Part of any flight’s record belongs to the clock rather than to the flight. B685 has one departure time, so this is what that time is worth.
On-time arrival rate. 10,894 departures from BUF are scheduled in the 6 AM–7 AM hour over the period, against 65,592 across the whole day.
B685 is scheduled out of BUF at 6:00 AM, in the 6 AM–7 AM bank. Departures from BUF in that hour arrive on time 87.6% of the time against 79.4% across the airport’s whole day — the slot alone is worth 8.2 points better before anything about this particular flight is considered.
The two airport figures cover every departure from BUF 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.

Data and methodology
Calculated by FlyerIntel from 1,122 records of B685 operating BUF → MCO, 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.
