These figures cover 267 flights between July 2025 and June 2026. Beyond the headline rate, 16.5% 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 2473 flies
B6 2473 flies JFK to CHS without a single fixed slot. Its most common scheduled departure was 15:44, used on 56 of 267 flights, with 15:50 (28 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 15:44 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and B6 2473 runs 4 points worse at 68.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
B6 2473 quarter by quarter
B6 2473 did not run the same all year. Its best quarter was Apr–Jun 2026 at 77.2% on time and its weakest Jul–Sep 2025 at 59.1%, a swing of 18 points on roughly 89 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, B6 2473 ranged from 63.4% on Friday to 75.0% on Monday. With about 38 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why B6 2473 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 6,788 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.
- 51%Late-arriving aircraft
- 28%Carrier
- 21%National Airspace System
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,788 reported delay minutes here, that single category outweighs weather by 51 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,788 delay minutes reported on B6 2473.
Cancellations run at 4.49%, against 1.81% nationally. That is roughly 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.5% 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.
The 636 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on one other city pair in the data, including JFK to MCO (1), but none flew often enough under B6 2473 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to CHS only.
One caution: this is a thin sample. 267 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 2473
For a booking, the cancellation rate is the figure to plan around on B6 2473: 4.49% of its 267 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.
