These figures cover 328 flights between July 2025 and June 2026. Beyond the headline rate, 10.4% 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 324 flies

B6 324 flies LAX to JFK without a single fixed slot. Its most common scheduled departure was 12:21, used on 64 of 328 flights, with 23:40 (50 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 12:21 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 324 runs 3 points worse at 75.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 324 quarter by quarter

Quarter by quarter B6 324 held fairly steady: 75.0% in Jul–Sep 2025, 71.6% in Oct–Dec 2025, 78.3% in Jan–Mar 2026 and 79.3% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, B6 324 did best on Friday at 89.6% on time and worst on Sunday at 68.1%. Each day rests on about 47 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 324 runs late

One category carries most of the weight here. National Airspace System accounts for 46% of the 5,638 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
46%
Carrier
29%
Late-arriving aircraft
24%

46% 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 2,618 minutes out of 5,638, against a national NAS share of 21%. The split is drawn from 5,638 delay minutes reported on B6 324.

Cancellations are rare at 0.30%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

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. 10.4% 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 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. 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.
