Because the same number has served different journeys, the statistics above describe only the route YX3580 currently operates. Blending them would produce an average of two different flights.
Why YX3580 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, fuelling — 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 YX3580 on EWR → GRR. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Data and methodology
Calculated by FlyerIntel from 303 records of YX3580 operating EWR → GRR, 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.
