crew, maintenance, boarding, fuelling — within the carrier’s control

Data and methodology
Calculated by FlyerIntel from 554 records of OO3964 operating DTW → MBS, 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.
