These figures cover 274 flights between September 2025 and August 2026. The median arrival is 9 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.

Share of 273 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 21 departures that left 15 minutes late or more, only 2 made it up before arrival. In the other direction, 19 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 CVG.

Delay causes
Why YX 3498 runs late
Late-arriving aircraft accounts for 49% of the 1,909 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 34%National Airspace System
- 16%Carrier
- 1%Extreme weather
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,909 reported delay minutes here, that single category outweighs weather by 34 to one. The split is drawn from 1,909 delay minutes reported on YX 3498.
Cancellations are rare at 0.36%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.4% 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 nine other city pairs in the data, including CVG to EWR (18), ORD to GSP (16) and GRB to ORD (10), but none flew often enough under YX 3498 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to CVG only.
One caution: this is a thin sample. 274 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 3498
For a booking, YX 3498 has one of the better records a US domestic flight can show: 86.1% on time and 0.36% cancelled. That is a base rate, not a promise about any single day.
