Where US DOT attributed the delay minutes on this flight.

Data and methodology
Calculated by FlyerIntel from 1,071 records of DL2423 operating ATL → OKC, 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.
