These figures cover 301 flights between September 2025 and August 2026. The median arrival is 13 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.

Across the year
YX 4657 quarter by quarter
YX 4657 did not run the same all year. Its best quarter was Apr–Jun 2026 at 93.3% on time and its weakest Jul–Sep 2026 at 83.3%, a swing of 10 points on roughly 75 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.

Delay causes
Why YX 4657 runs late
Carrier accounts for 64% of the 2,645 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Carrier
- 14%Late-arriving aircraft
- 14%National Airspace System
- 8%Extreme weather
The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,698 of the 2,645 delay minutes reported here. The split is drawn from 2,645 delay minutes reported on YX 4657.
Cancellations run at 3.65%, against 1.89% nationally. That is roughly one flight in 25 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
5.5% 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 589 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 three other city pairs in the data, including BOS to LGA (38), DCA to GSP (6) and GSP to DCA (6), but none flew often enough under YX 4657 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CVG to JFK only.
One caution: this is a thin sample. 301 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 YX 4657
For a booking, the cancellation rate is the figure to plan around on YX 4657: 3.65% of its 301 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.
