Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| B6455 | 77.4% | 1.79% | -7 min | 9.6% | 615 |
| JetBlue on BOS → DCA | 74.1% | 2.79% | -6 min | 10.4% | 10,090 |
| All BOS → DCA flights | 77.1% | 2.92% | -7 min | 9.4% | 29,323 |
B6455 has cancelled 1.79% of its scheduled departures (11 of 615), against 2.92% for all BOS → DCA flights — this specific departure cancels 1.1 percentage points less 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 B6455 specifically, not about the route it flies.

Why B6455 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 B6455 on BOS → DCA. 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 B6455 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, B6455 pushed back an average of 38 minutes late; when it came in on time or early, an average of 0 minutes late.
Matched by tail number to the aircraft’s previous flight into BOS: 515 of 604 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 |
|---|---|---|---|
| B6455 | 25% | 39% | 11% |
| Network, same turn | 17% | 69% | 9% |
60 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 B6455’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often B6455 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves BOS late, does that still matter by the time it reaches DCA?
B6455 pushes back an average of 13.0 minutes late and reaches the gate at DCA an average of 10.0 minutes late. The 3.0 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 18.9 minutes on the taxiways at BOS, 1.3 minutes shorter than a typical BOS departure in the same hour.
On arrival at DCA, B6455 spends 6.9 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 about what any arrival at DCA spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 29,137 BOS departures. Taxi-in is landing to gate, set against 447,280 arrivals at DCA. More on taxi time.

The hour it leaves BOS
B6455 has one departure time, 9:00 AM, so this is what that hour at BOS is worth.
On-time arrival rate. 29,137 departures from BOS are scheduled in the 9 AM–10 AM hour over the period, against 454,081 across the whole day.
B6455 is scheduled out of BOS at 9:00 AM, in the 9 AM–10 AM bank. Departures from BOS in that hour arrive on time 84.7% of the time against 77.0% across the airport’s whole day — the slot alone is worth 7.7 points better before anything about this particular flight is considered.
Both airport figures cover every destination from BOS, 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.
54 min late
against a median of 7 min early
B6455 has an average that understates its risk: a typical arrival is 7 min early, but the worst tenth are 61 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 615 records of B6455 operating BOS → DCA, 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.
