Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX5655 | 65.5% | 3.71% | -3 min | 14.1% | 620 |
| Republic Airways on BOS → CLE | 82.8% | 2.01% | -10 min | 6.7% | 2,735 |
| All BOS → CLE flights | 79.8% | 1.94% | -9 min | 8.2% | 5,401 |
YX5655 has cancelled 3.71% of its scheduled departures (23 of 620), against 1.94% for all BOS → CLE flights — this specific departure cancels 1.8 percentage points more 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 YX5655 specifically, not about the route it flies.
14.1% of YX5655’s arrivals were an hour or more late, against 8.2% across BOS → CLE, so the long delays are more common on this number than on the route.

Why YX5655 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 YX5655 on BOS → CLE. 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 YX5655 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, YX5655 pushed back an average of 58 minutes late; when it came in on time or early, an average of 3 minutes early.
Matched by tail number to the aircraft’s previous flight into BOS: 579 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 | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| YX5655 | 34% | 78% | 6% |
| Network, same turn | 18% | 85% | 10% |
47 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 45 to 59 minutes. How often YX5655’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often YX5655 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 CLE?
YX5655 pushes back an average of 20.0 minutes late and reaches the gate at CLE an average of 15.1 minutes late. The 4.9 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 23.7 minutes on the taxiways at BOS, 5.7 minutes longer than a typical BOS departure in the same hour.
On arrival at CLE, YX5655 spends 10.3 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 1.9 minutes longer than a typical CLE arrival (8.5 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 7,264 BOS departures. Taxi-in is landing to gate, set against 130,623 arrivals at CLE. More on taxi time.

The hour it leaves BOS
YX5655 has one departure time, 9:20 PM, so this is what that hour at BOS is worth.
On-time arrival rate. 7,264 departures from BOS are scheduled in the 9 PM–10 PM hour over the period, against 454,081 across the whole day.
YX5655 is scheduled out of BOS at 9:20 PM, in the 9 PM–10 PM bank. Departures from BOS in that hour arrive on time 63.6% of the time against 77.0% across the airport’s whole day — the slot alone is worth 13.4 points worse 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.
78 min late
against a median of 3 min early
YX5655 has an average that understates its risk: a typical arrival is 3 min early, but the worst tenth are 81 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 620 records of YX5655 operating BOS → CLE, 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.
