Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4567, 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 4567 sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land about 50 minutes behind schedule. That rests on 270 flights, with a median arrival 2 minutes early.

These figures cover 270 flights between July 2025 and June 2026. The median arrival is 2 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 4567 flies

YX 4567 flies BNA to RDU without a single fixed slot. Its most common scheduled departure was 13:15, used on 54 of 270 flights, with 12:35 (41 flights) and 13:29 (32 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 13:15 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and YX 4567 runs 3 points worse at 75.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

YX 4567 quarter by quarter

YX 4567 did not run the same all year. Its best quarter was Jan–Mar 2026 at 85.7% on time and its weakest Oct–Dec 2025 at 63.5%, a swing of 22 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.

By weekday, YX 4567 ranged from 71.1% on Sunday to 82.4% on Saturday. With about 39 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 4567 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 3,154 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.

  • Late-arriving aircraft
    43%
  • National Airspace System
    28%
  • Carrier
    22%
  • Extreme weather
    7%

43% 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 3,154 reported delay minutes here, that single category outweighs weather by 6 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 3,154 delay minutes reported on YX 4567.

Cancellations run at 2.59%, against 1.81% nationally. That is about one flight in 40 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

7.3% 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 50 minutes, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including BOS to LGA (38), but none flew often enough under YX 4567 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BNA to RDU only.

One caution: this is a thin sample. 270 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 4567

For a booking, the cancellation rate is the figure to plan around on YX 4567: 2.59% of its 270 scheduled flights did not operate. A late arrival costs about 50 minutes, but a cancellation costs the day, so leave a later option open.
