These figures cover 314 flights between July 2025 and June 2026. The median arrival is 11 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.

Schedule

When UA 601 flies

UA 601 flies CLE to EWR without a single fixed slot. Its most common scheduled departure was 07:00, used on 75 of 314 flights, with 07:15 (66 flights) and 06:20 (38 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 601 runs 5 points better at 94.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

UA 601 quarter by quarter

By weekday, UA 601 ranged from 88.9% on Thursday to 97.7% on Wednesday. With about 45 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 601 runs late

One category carries most of the weight here. National Airspace System accounts for 82% of the 966 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
14%

Late-arriving aircraft
1%

82% 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 788 minutes out of 966, against a national NAS share of 21%. The split is drawn from 966 delay minutes reported on UA 601.

Cancellations sit at 1.27% against a national 1.81%, 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 1.0% land an hour or more behind schedule, against 8.1% 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 seven other city pairs in the data, including DEN to MSO (31), EWR to CLT (28) and EWR to SLC (24), 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. 314 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, UA 601 has one of the better records a US domestic flight can show: 94.2% on time and 1.27% cancelled. That is a base rate, not a promise about any single day.
