Other routes YX4532 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
Because the same number has served different journeys, the statistics above describe only the route YX4532 currently operates. Blending them would produce an average of two different flights.
Why YX4532 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding, fuelling — within the carrier’s control

weather severe enough to stop this flight specifically
screening or terminal security incidents

Data and methodology
Calculated by FlyerIntel from 808 records of YX4532 operating RDU → PIT, 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.
