Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4657, check with Republic Airways. Republic Airways flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.
YX 4657 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 15 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 301 flights, with a median arrival 13 minutes early.
Set against the rest of the country, YX 4657's record is 15 points better than the US average of 77.6%. That gap is worth roughly 148 fewer late arrivals for every thousand flights.

These figures cover 301 flights between July 2025 and June 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.
Schedule
When YX 4657 flies
YX 4657 flies CVG to JFK without a single fixed slot. Its most common scheduled departure was 09:25, used on 55 of 301 flights, with 05:47 (40 flights) and 09:30 (40 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 09:2555 flights18.3%
- Departs 05:4740 flights13.3%
- Departs 09:3040 flights13.3%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:25 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 4657 runs 8 points better at 92.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
YX 4657 quarter by quarter
Quarter by quarter YX 4657 held fairly steady: 94.5% in Jul–Sep 2025, 90.9% in Oct–Dec 2025, 91.0% in Jan–Mar 2026 and 93.3% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202592 flights94.5%
- Oct–Dec 202578 flights90.9%
- Jan–Mar 202685 flights91.0%
- Apr–Jun 202646 flights93.3%
Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, YX 4657 did best on Tuesday at 97.6% on time and worst on Sunday at 85.0%. Each day rests on about 43 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why YX 4657 runs late
One category carries most of the weight here. Carrier accounts for 64% of the 2,566 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.
- 64%Carrier
- 18%Late-arriving aircraft
- 10%National Airspace System
- 8%Extreme weather
The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,630 of the 2,566 delay minutes reported here. The split is drawn from 2,566 delay minutes reported on YX 4657.
Cancellations run at 3.32%, 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
Badly late arrivals are rare here: only 4.8% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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. 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 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: 3.32% of its 301 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
