These figures cover 347 flights between September 2025 and August 2026. The median arrival is 14 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Delay causes

Why B6 1524 runs late

Late-arriving aircraft accounts for 58% of the 4,712 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
58%
Carrier
33%
National Airspace System

58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,712 reported delay minutes here, that single category outweighs weather by 58 to one. The split is drawn from 4,712 delay minutes reported on B6 1524.

Cancellations run at 3.75%, against 1.89% nationally. That is about one flight in 25 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

7.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

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 347 flights under B6 1524 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. 347 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 1524

For a booking, the cancellation rate is the figure to plan around on B6 1524: 3.75% of its 347 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.
