Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5655, 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 5655 draws a D−. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is about an hour behind schedule. Build slack into anything you connect to. That rests on 322 flights, with a median arrival 2 minutes early.

The national on-time rate over the same period is 77.6%, so YX 5655 runs 16 points behind the country as a whole. Across a thousand flights that is about 165 extra late arrivals.

These figures cover 322 flights between July 2025 and June 2026. Beyond the headline rate, 14.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When YX 5655 flies

YX 5655 flies BOS to CLE without a single fixed slot. Its most common scheduled departure was 20:50, used on 59 of 322 flights, with 19:15 (50 flights) and 21:20 (48 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 20:50 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and YX 5655 runs 9 points worse at 61.1%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

YX 5655 quarter by quarter

Quarter by quarter YX 5655 held fairly steady: 59.2% in Jul–Sep 2025, 58.5% in Oct–Dec 2025, 63.8% in Jan–Mar 2026 and 63.1% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202578 flights59.2%
Oct–Dec 202583 flights58.5%
Jan–Mar 202675 flights63.8%

Scale runs 50% to 70%. Rows with fewer than 30 flights show a dash.

By weekday, YX 5655 did best on Friday at 68.6% on time and worst on Tuesday at 54.9%. Each day rests on about 46 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 5655 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 7,336 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.

51% 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 7,336 reported delay minutes here, that single category outweighs weather by 51 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 7,336 delay minutes reported on YX 5655.

Cancellations run at 4.66%, against 1.81% nationally. That is about one flight in twenty 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 563 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 one other city pair in the data, including BOS to CVG (11), but none flew often enough under YX 5655 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOS to CLE only.

One caution: this is a thin sample. 322 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 5655

For a booking, the cancellation rate is the figure to plan around on YX 5655: 4.66% of its 322 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
