Delay causes
What held BOS up in October
Late-arriving aircraft accounts for 59% of the 242,000 delay minutes carriers reported here, and the remaining four split what is left.

59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 242,000 reported delay minutes here, that single category outweighs weather by 45 to one. The split is drawn from 241,666 reported delay minutes.
Cancellations sit at 1.51% against a national 0.53%, which is ordinary. Diversions add another 0.21%.
10.5% of arrivals land a full hour or more behind schedule, against 6.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
