Why OO4166 runs late

Where US DOT attributed the delay minutes on this flight.

Share of the delay minutes US DOT attributed to each cause for OO4166 on DTW → ATW. 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 604 records of OO4166 operating DTWATW, 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.
