These figures cover 307 flights between September 2025 and August 2026. The median arrival is 3 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.

51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,671 reported delay minutes here, that single category outweighs weather by 20 to one. The split is drawn from 5,671 delay minutes reported on F9 4732.

Connections and routes
What a delay on this flight costs
7.3% 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.
The 760 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 307 flights under F9 4732 in the data flew ATL 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. 307 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.
