These figures cover 280 flights between September 2025 and August 2026. The median arrival is 8 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 320 runs late
Carrier accounts for 45% of the 4,015 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 30%Late-arriving aircraft
- 25%National Airspace System
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,818 of the 4,015 delay minutes reported here. The split is drawn from 4,015 delay minutes reported on B6 320.
Cancellations run at 5.36%, against 1.89% nationally. That is about one flight in twenty 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
6.8% 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 an hour and a half, 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 280 flights under B6 320 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. 280 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 320
For a booking, the cancellation rate is the figure to plan around on B6 320: 5.36% of its 280 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
