Historical statistics for July 2025 to June 2026, not live status. For today’s UA 674, check with United Airlines.
UA 674 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 317 flights, with a median arrival 7 minutes early.
Set against the rest of the country, UA 674's record is 12 points better than the US average of 77.6%. That gap is worth roughly 115 fewer late arrivals for every thousand flights.

These figures cover 317 flights between July 2025 and June 2026. The median arrival is 7 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 674 flies
UA 674 flies CHS to EWR without a single fixed slot. Its most common scheduled departure was 11:20, used on 48 of 317 flights, with 11:18 (41 flights) and 11:00 (40 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 11:20 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 674 runs 10 points better at 89.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 674 quarter by quarter
Quarter by quarter UA 674 held fairly steady: 86.0% in Jul–Sep 2025, 85.9% in Oct–Dec 2025, 92.9% in Jan–Mar 2026 and 91.9% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, UA 674 did best on Tuesday at 96.0% on time and worst on Sunday at 75.0%. Each day rests on about 45 flights, so a gap of 21 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 674 runs late
One category carries most of the weight here. National Airspace System accounts for 50% of the 3,694 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.
- 50%National Airspace System
- 36%Carrier
- 14%Late-arriving aircraft
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,332 of the 3,694 delay minutes reported here. The split is drawn from 3,694 delay minutes reported on UA 674.
Cancellations sit at 1.26% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on eight other city pairs in the data, including EWR to DFW (36), IAD to CLE (16) and SFO to EUG (5), 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. 317 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 674
For a booking, UA 674 has one of the better records a US domestic flight can show: 89.1% on time and 1.26% cancelled. That is a base rate, not a promise about any single day.
