Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4735, 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 4735 lands a B−, 4 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 292 flights, with a median arrival 7 minutes early.

These figures cover 292 flights between July 2025 and June 2026. The median arrival is 7 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 4735 flies
YX 4735 flies LGA to BNA without a single fixed slot. Its most common scheduled departure was 08:40, used on 46 of 292 flights, with 09:09 (38 flights) and 09:16 (32 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 08:4046 flights15.8%
- Departs 09:0938 flights13.0%
- Departs 09:1632 flights11.0%
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 08:40 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 4735 runs 3 points worse at 81.1%. 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 4735 quarter by quarter
YX 4735 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.9% on time and its weakest Oct–Dec 2025 at 76.7%, a swing of 14 points on roughly 73 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 202578 flights90.9%
- Oct–Dec 202587 flights76.7%
- Jan–Mar 202683 flights77.0%
- Apr–Jun 202644 flights79.5%
Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, YX 4735 ranged from 75.0% on Friday to 84.8% on Wednesday. With about 42 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why YX 4735 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 2,584 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.
- 46%Late-arriving aircraft
- 27%National Airspace System
- 23%Carrier
- 4%Extreme weather
46% 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 2,584 reported delay minutes here, that single category outweighs weather by 12 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 2,584 delay minutes reported on YX 4735.
Cancellations run at 3.77%, against 1.81% nationally. That is about 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
Badly late arrivals are rare here: only 4.6% 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 764 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 PHL to BUF (25) and BUF to PHL (25), but none flew often enough under YX 4735 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to BNA only.
One caution: this is a thin sample. 292 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 4735
For a booking, the cancellation rate is the figure to plan around on YX 4735: 3.77% of its 292 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
