24 of 88 late departures made up the time and arrived on time, 27% of them. In the other direction, 18 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at JFK.
The worst days

| Date | Arrived late by | Largest filed cause |

Delay causes
Why B6 324 runs late
National Airspace System accounts for 44% of the 5,260 delay minutes carriers reported here, and the remaining four split what is left.
- 44%National Airspace System
- 30%Carrier
- 26%Late-arriving aircraft
44% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,332 minutes out of 5,260, against a national NAS share of 21%. The split is drawn from 5,260 delay minutes reported on B6 324.
Cancellations sit at 1.89% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
10.0% 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 2,475 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 317 flights under B6 324 in the data flew LAX 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. 317 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.
What to do with this
