Why YX4804 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
weather severe enough to stop this flight specifically

Data and methodology
Calculated by FlyerIntel from 433 records of YX4804 operating JFK → RDU, 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.
