Why MSN → EWR runs late
Where US DOT attributed the delay minutes on this route.
crew, maintenance, boarding, fuelling — within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for MSN → EWR. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
A route inherits the problems of both ends and of the aircraft flying it. A large share attributed to late-arriving aircraft usually means the departure sits late in a busy rotation rather than that anything about this city pair is difficult, which is why the same route often performs very differently at different times of day.

Data and methodology
All figures on this page are calculated by FlyerIntel from 1,158 MSN → EWR flight records published by the US DOT Bureau of Transportation Statistics, covering July 2023 – June 2026. A flight is counted as delayed when it arrives 15 or more minutes after its scheduled arrival time, following BTS methodology. Cancelled and diverted flights have no arrival time and are excluded from on-time rates rather than counted as late.
