These figures cover 319 flights between September 2025 and August 2026. The median arrival is 8 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
UA 674 quarter by quarter
UA 674 did not run the same all year. Its best quarter was Jan–Mar 2026 at 92.9% on time and its weakest Jul–Sep 2026 at 82.0%, a swing of 11 points on roughly 80 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, UA 674 did best on Wednesday at 96.0% on time and worst on Sunday at 81.2%. Each day rests on about 46 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

The worst days

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 10 hours 53 minutes | Carrier |
| 2 November 2025 | 3 hours 50 minutes | National Airspace System |
| 14 December 2025 | 3 hours 45 minutes | Late-arriving aircraft |

Delay causes
Why UA 674 runs late
National Airspace System accounts for 44% of the 3,055 delay minutes carriers reported here, and the remaining four split what is left.
- 44%National Airspace System
- 32%Carrier
- 24%Late-arriving aircraft
44% 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 1,336 minutes out of 3,055, against a national NAS share of 21%. The split is drawn from 3,055 delay minutes reported on UA 674.
Cancellations sit at 1.57% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.4% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The 628 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on eight other city pairs in the data, including EWR to DFW (36), IAD to CLE (16) and ORD to MSY (4), but none flew often enough under UA 674 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CHS to EWR only.
One caution: this is a thin sample. 319 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
