These figures cover 348 flights between July 2025 and June 2026. Beyond the headline rate, 8.6% 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 2474 flies
B6 2474 flies CHS to JFK without a single fixed slot. Its most common scheduled departure was 11:00, used on 64 of 348 flights, with 11:10 (53 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 11:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 2474 runs level with that at 78.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
B6 2474 quarter by quarter
B6 2474 did not run the same all year. Its best quarter was Apr–Jun 2026 at 84.3% on time and its weakest Jan–Mar 2026 at 73.1%, a swing of 11 points on roughly 87 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 2474 did best on Tuesday at 84.4% on time and worst on Sunday at 63.3%. Each day rests on about 50 flights, so a gap of 21 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 2474 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 57% of the 5,076 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.
- 57%Late-arriving aircraft
- 33%Carrier
- 9%National Airspace System
57% 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 5,076 reported delay minutes here, that single category outweighs weather by 57 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 5,076 delay minutes reported on B6 2474.
Cancellations run at 3.16%, against 1.81% nationally. That is about one flight in 30 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
8.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 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.
Every one of the 348 flights under B6 2474 in the data flew CHS 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. 348 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 2474
For a booking, the cancellation rate is the figure to plan around on B6 2474: 3.16% of its 348 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.
