These figures cover 280 flights between September 2025 and August 2026. The median arrival is 13 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.

Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.1% 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 eight other city pairs in the data, including BUF to IAD (50), BDL to IAD (24) and IAD to LGA (18), but none flew often enough under YX 3430 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CMH to IAD only.
One caution: this is a thin sample. 280 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 3430
For a booking, YX 3430 has one of the better records a US domestic flight can show: 94.9% on time and 1.07% cancelled. That is a base rate, not a promise about any single day.
