Share of 319 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 117 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 16 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at CLE.

The latest arrival of the period was on 7 July 2026, 4 hours 14 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across July, December and October, with no single month standing out.

Delay causes
Why YX 5655 runs late
Late-arriving aircraft accounts for 49% of the 8,120 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 34%Carrier
- 15%National Airspace System
- 2%Extreme weather
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,120 reported delay minutes here, that single category outweighs weather by 21 to one. The split is drawn from 8,120 delay minutes reported on YX 5655.
Cancellations run at 3.61%, against 1.89% nationally. That is about one flight in 30 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
16.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
The same number turns up on one other city pair in the data, including BOS to CVG (1), 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. 332 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: 3.61% of its 332 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
