Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4677, 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 4677 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 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 265 flights, with a median arrival 12 minutes early.

Set against the rest of the country, YX 4677's record is 13 points better than the US average of 77.6%. That gap is worth roughly 129 fewer late arrivals for every thousand flights.

These figures cover 265 flights between July 2025 and June 2026. The median arrival is 12 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 4677 flies

YX 4677 flies CLE to LGA without a single fixed slot. Its most common scheduled departure was 06:49, used on 38 of 265 flights, with 06:17 (32 flights) and 06:40 (27 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 06:49 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 4677 runs level with that at 90.5%. 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 4677 quarter by quarter

Quarter by quarter YX 4677 held fairly steady: 89.4% in Jul–Sep 2025, 89.7% in Oct–Dec 2025, 92.5% in Jan–Mar 2026 and 90.1% in Apr–Jun 2026. A spread of 3 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202547 flights89.4%
Oct–Dec 202561 flights89.7%

By weekday, YX 4677 did best on Friday at 100.0% on time and worst on Thursday at 86.7%. Each day rests on about 38 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 4677 runs late

One category carries most of the weight here. Carrier accounts for 56% of the 1,719 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.

Carrier
56%
National Airspace System
39%
Late-arriving aircraft
5%

39% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 668 minutes out of 1,719, against a national NAS share of 21%. The split is drawn from 1,719 delay minutes reported on YX 4677.

Cancellations run at 4.15%, 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 3.6% 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 same number turns up on five other city pairs in the data, including MSP to ORD (11), SAV to DCA (3) and DCA to SAV (3), but none flew often enough under YX 4677 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CLE to LGA only.

One caution: this is a thin sample. 265 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 4677

For a booking, the cancellation rate is the figure to plan around on YX 4677: 4.15% of its 265 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
