Other routes B62233 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
Because the same number has served different journeys, the statistics above describe only the route B62233 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.
61 min late
against a median of 4 min early
B62233 is a flight whose average understates its risk: a typical day arrives 4 min early, but the worst tenth of days are 65 minutes worse than that. If the day has something unmissable in it, the median is the wrong number to plan against.
Percentiles over 440 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.
Why B62233 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding, fuelling — within the carrier’s control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically

Data and methodology
Calculated by FlyerIntel from 440 records of B62233 operating BOS → SFO, 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.
