Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4712, 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 4712 lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 319 flights, with a median arrival 9 minutes early.
Set against the rest of the country, YX 4712's record is 5 points better than the US average of 77.6%. That gap is worth roughly 53 fewer late arrivals for every thousand flights.

These figures cover 319 flights between July 2025 and June 2026. The median arrival is 9 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 4712 flies
YX 4712 flies BNA to JFK without a single fixed slot. Its most common scheduled departure was 12:00, used on 52 of 319 flights, with 08:33 (38 flights) and 08:55 (37 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 12:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and YX 4712 runs 4 points better at 82.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
YX 4712 quarter by quarter
YX 4712 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.5% on time and its weakest Jan–Mar 2026 at 72.3%, a swing of 21 points on roughly 80 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.
- Jul–Sep 202592 flights93.5%
- Oct–Dec 202590 flights81.8%
- Jan–Mar 202690 flights72.3%
- Apr–Jun 202647 flights83.0%
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, YX 4712 did best on Tuesday at 90.9% on time and worst on Friday at 71.7%. Each day rests on about 46 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Delay causes
Why YX 4712 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 3,156 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.
- 52%Late-arriving aircraft
- 29%National Airspace System
- 18%Carrier
- 1%Extreme weather
52% 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 3,156 reported delay minutes here, that single category outweighs weather by 52 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 3,156 delay minutes reported on YX 4712.
Cancellations sit at 2.19% against a national 1.81%, which is ordinary. Diversions add another 0.63%.
Connections and routes
What a delay on this flight costs
6.1% 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 about an hour, which a normal layover absorbs.
The 765 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 two other city pairs in the data, including BOS to CMH (42) and CMH to BOS (38), but none flew often enough under YX 4712 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BNA to JFK only.
One caution: this is a thin sample. 319 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 4712
For a booking, read YX 4712 as 82.9% on time with 2.19% cancelled over 319 flights. Those are rates from the past twelve months, not a forecast for any particular day.
