- 45%Late-arriving aircraft
- 42%Carrier
- 14%National Airspace System
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,216 reported delay minutes here, that single category outweighs weather by 45 to one. The split is drawn from 6,216 delay minutes reported on B6 816.
Cancellations sit at 1.72% against a national 1.89%, which is ordinary. Diversions add another 0.86%.
Connections and routes
What a delay on this flight costs
9.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 2,586 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 348 flights under B6 816 in the data flew SFO to JFK. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 348 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
