Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| YX5698 | 90.5% | 1.98% | -11 min | 3.7% | 605 |
| Republic Airways on DCA → BOS | 81.9% | 3.27% | -11 min | 7.7% | 12,394 |
| All DCA → BOS flights | 75.8% | 3.07% | -8 min | 11.1% | 29,323 |
YX5698 has cancelled 1.98% of its scheduled departures (12 of 605), against 3.07% for all DCA → BOS 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 YX5698 specifically, not about the route it flies.
3.7% of YX5698’s arrivals were an hour or more late, against 11.1% across DCA → BOS, so the long delays are less common on this number than on the route.

Why YX5698 runs late
Where US DOT attributed the delay minutes on this flight.
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
the inbound aircraft was late, so this flight started late

Does a late aircraft delay this flight?
How often the plane that flies YX5698 comes in late, and what that does to the departure.
YX5698 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.4 hours on the ground at DCA, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, YX5698 pushed back an average of 0 minutes late; when it came in on time or early, an average of 1 minute early.
Matched by tail number to the aircraft’s previous flight into DCA: 525 of 593 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 |
|---|---|---|---|
| YX5698 | 28% | 10% | 9% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less here than on a same-day turn.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often YX5698’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often YX5698 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves DCA late, does that still matter by the time it reaches BOS?
YX5698 pushes back an average of 2.6 minutes late and reaches the gate at BOS an average of 4.7 minutes early. The 7.4 minutes between those two figures are slack the published schedule already carries, so on average a late pushback on this flight is made up before the gate. It spends 19.1 minutes on the taxiways at DCA, 1.2 minutes longer than a typical DCA departure in the same hour.
On arrival at BOS, YX5698 spends 12.5 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 3.5 minutes longer than a typical BOS arrival (9.0 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 32,443 DCA departures. Taxi-in is landing to gate, set against 454,075 arrivals at BOS. More on taxi time.

The hour it leaves DCA
YX5698 has one departure time, 6:59 AM, so this is what that hour at DCA is worth.
On-time arrival rate. 32,443 departures from DCA are scheduled in the 6 AM–7 AM hour over the period, against 447,230 across the whole day.
YX5698 is scheduled out of DCA at 6:59 AM, in the 6 AM–7 AM bank. Departures from DCA in that hour arrive on time 90.9% of the time against 76.3% across the airport’s whole day — the slot alone is worth 14.6 points better before anything about this particular flight is considered.
Both airport figures cover every destination from DCA, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

Data and methodology
Calculated by FlyerIntel from 605 records of YX5698 operating DCA → BOS, 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.
