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 2026 at 60.0%, a swing of 17 points on roughly 90 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.

Share of 252 completed flights by arrival against schedule.
10 of 66 late departures made up the time and arrived on time, 15% of them. In the other direction, 16 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 CHS.
The worst days
Worst days for B6 2473
The latest arrival of the period was on 10 June 2026, 5 hours 58 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 |
|---|---|---|
| 10 June 2026 | 5 hours 58 minutes | Carrier |
| 5 November 2025 | 4 hours 44 minutes | Carrier |
| 8 August 2026 | 4 hours 24 minutes | Late-arriving aircraft |

Delay causes
Why B6 2473 runs late
Late-arriving aircraft accounts for 50% of the 5,599 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 31%Carrier
- 19%National Airspace System
- 1%Extreme weather
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,599 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 5,599 delay minutes reported on B6 2473.
Cancellations run at 7.01%, against 1.89% nationally. That is about 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
13.9% 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 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.
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. 271 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: 7.01% of its 271 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.
