Percentiles over 340 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.

Why OO3945 runs late

Share of the delay minutes US DOT attributed to each cause for OO3945 on BNA → AUS. 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 340 records of OO3945 operating BNAAUS, 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.
