Across the year
B6 524 quarter by quarter
B6 524 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.2% on time and its weakest Jan–Mar 2026 at 63.6%, a swing of 28 points on roughly 84 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Share of 325 completed flights by arrival against schedule.
16 of 67 late departures made up the time and arrived on time, 24% 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
Worst days for B6 524
The latest arrival of the period was on 14 December 2025, 7 hours 34 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 December 2025 | 7 hours 34 minutes | Late-arriving aircraft |
| 12 December 2025 | 4 hours 59 minutes | Late-arriving aircraft |

Delay causes
Why B6 524 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,442 reported delay minutes.
- 40%National Airspace System
- 38%Late-arriving aircraft
- 22%Carrier
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,442 reported delay minutes here, that single category outweighs weather by 38 to one. The split is drawn from 5,442 delay minutes reported on B6 524.
Cancellations run at 2.97%, against 1.89% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
10.2% 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 337 flights under B6 524 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. 337 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
Booking B6 524
For a booking, the cancellation rate is the figure to plan around on B6 524: 2.97% of its 337 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
