Because the same number has served different journeys, the statistics above describe only the route AA677 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
92 min late
against a median of 3 min late
AA677 is a flight whose average understates its risk: a typical day arrives 3 min late, but the worst tenth of days are 89 minutes worse than that. If the day has something unmissable in it, the median is the wrong number to plan against.
Percentiles over 300 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.
Why AA677 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding, fuelling — within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for AA677 on ORD → MSY. 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 300 records of AA677 operating ORD → MSY, 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.
