When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
94 min late
against a median of 10 min late
B622 is a flight whose average understates its risk: a typical day arrives 10 min late, but the worst tenth of days are 84 minutes worse than that. If the day has something unmissable in it, the median is the wrong number to plan against.

weather severe enough to stop this flight specifically
screening or terminal security incidents

Data and methodology
Calculated by FlyerIntel from 414 records of B622 operating PBI → BOS, 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.
