Why AA578 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding, fuelling — within the carrier’s control
weather severe enough to stop this flight specifically
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for AA578 on DFW → JFK. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Other departures on DFW → JFK
Same airports, same journey — and not the same odds of arriving on time.

Data and methodology
Calculated by FlyerIntel from 593 records of AA578 operating DFW → JFK, 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.
