These figures cover 328 flights between July 2025 and June 2026. Beyond the headline rate, 11.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When B6 524 flies

B6 524 flies LAX to JFK without a single fixed slot. Its most common scheduled departure was 13:30, used on 45 of 328 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 13:30 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 524 runs level with that at 77.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

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 82 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.

By weekday, B6 524 did best on Saturday at 84.8% on time and worst on Sunday at 66.0%. Each day rests on about 47 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 524 runs late

One category carries most of the weight here. National Airspace System accounts for 42% of the 5,995 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

National Airspace System
42%
Late-arriving aircraft
39%
Carrier
19%

39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,995 reported delay minutes here, that single category outweighs weather by 39 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,995 delay minutes reported on B6 524.

Cancellations sit at 2.13% against a national 1.81%, which is ordinary. Diversions add another 0.91%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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 328 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. 328 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.
