These figures cover 354 flights between September 2025 and August 2026. The median arrival is 10 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.

Delay causes
Why UA 601 runs late
National Airspace System accounts for 62% of the 1,442 delay minutes carriers reported here, and the remaining four split what is left.
- 62%National Airspace System
- 20%Carrier
- 17%Extreme weather
- 1%Late-arriving aircraft
Extreme weather accounts for 17% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.7 times the usual weather exposure. The split is drawn from 1,442 delay minutes reported on UA 601.
Cancellations sit at 1.98% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.7% 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 EWR to CLT (46), EWR to SLC (24) and EWR to BNA (20), but none flew often enough under UA 601 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CLE to EWR only.
One caution: this is a thin sample. 354 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 UA 601
For a booking, read UA 601 as 92.8% on time with 1.98% cancelled over 354 flights. Those are rates from the past twelve months, not a forecast for any particular day.
