These figures cover 333 flights between September 2025 and August 2026. The median arrival is 15 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.

Across the year

YX 3641 quarter by quarter

YX 3641 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.5% on time and its weakest Oct–Dec 2025 at 76.5%, a swing of 15 points on roughly 83 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 3641 ranged from 80.4% on Thursday to 92.2% on Friday. With about 48 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Share of 323 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 26 departures that left 15 minutes late or more, only 3 made it up before arrival. In the other direction, 21 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 3641 runs late

National Airspace System accounts for 52% of the 2,430 delay minutes carriers reported here, and the remaining four split what is left.

Carrier

Extreme weather

52% 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 1,262 minutes out of 2,430, against a national NAS share of 21%. The split is drawn from 2,430 delay minutes reported on YX 3641.

Cancellations sit at 2.40% against a national 1.89%, which is ordinary. Diversions add another 0.60%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.0% land an hour or more behind schedule, against 8.3% 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 six other city pairs in the data, including ATL to EWR (7), BOS to EWR (7) and RDU to EWR (5), but none flew often enough under YX 3641 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. 333 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 3641

For a booking, read YX 3641 as 86.4% on time with 2.40% cancelled over 333 flights. Those are rates from the past twelve months, not a forecast for any particular day.
