Share of 260 completed flights by arrival against schedule.
17 of 109 late departures made up the time and arrived on time, 16% of them. In the other direction, 15 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ATL.
The worst days
Worst days for B6 719
The latest arrival of the period was on 4 September 2025, 11 hours 32 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 September 2025 | 11 hours 32 minutes | Carrier |
| 4 April 2026 | 4 hours 43 minutes | Late-arriving aircraft |
| 10 November 2025 | 4 hours 36 minutes | Carrier |

Delay causes
Why B6 719 runs late
Carrier accounts for 43% of the 8,003 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Carrier
- 43%Late-arriving aircraft
- 14%National Airspace System
- 0%Security
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,003 reported delay minutes here, that single category outweighs weather by 43 to one. The split is drawn from 8,003 delay minutes reported on B6 719.
Cancellations run at 6.14%, against 1.89% nationally. That is roughly one flight in fifteen 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
16.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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 277 flights under B6 719 in the data flew JFK to ATL. 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. 277 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 719
For a booking, the cancellation rate is the figure to plan around on B6 719: 6.14% of its 277 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.
