Share of 317 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 45 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 28 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 CMH.

Delay causes
Why YX 3545 runs late
Late-arriving aircraft accounts for 49% of the 6,267 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 29%Carrier
- 22%National Airspace System
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,267 reported delay minutes here, that single category outweighs weather by 49 to one. The split is drawn from 6,267 delay minutes reported on YX 3545.
Cancellations run at 6.76%, against 1.89% nationally. That is about one flight in fifteen 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
8.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The same number turns up on one other city pair in the data, including IAD to EYW (19), but none flew often enough under YX 3545 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to CMH only.
One caution: this is a thin sample. 340 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 3545
For a booking, the cancellation rate is the figure to plan around on YX 3545: 6.76% of its 340 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
