Because the same number has served different journeys, the statistics above describe only the route OO5029 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.
110 min late
against a median of 12 min early
OO5029 is a flight whose average understates its risk: a typical day arrives 12 min early, but the worst tenth of days are 122 minutes worse than that. If the day has something unmissable in it, the median is the wrong number to plan against.
Percentiles over 966 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.
Why OO5029 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding, fuelling — within the carrier’s control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for OO5029 on JST → ORD. 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 966 records of OO5029 operating JST → ORD, 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.
