Because the same number has served different journeys, the statistics above describe only the route YX5689 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
69 min late
against a median of 0 min early
YX5689 is a flight whose average understates its risk: a typical day arrives 0 min early, but the worst tenth of days are 69 minutes worse than that. If the day has something unmissable in it, the median is the wrong number to plan against.
Percentiles over 664 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.
Why YX5689 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding, fuelling — within the carrier’s control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for YX5689 on BOS → DCA. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Other departures on BOS → DCA
Same airports, same journey — and not the same odds of arriving on time.

| YX5672 | Republic Airways | 87.2% | 12 min early | 668 |

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 664 records of YX5689 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 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.
