Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2350, check with United Airlines.
UA 2350 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 364 flights, with a median arrival 1 minute early.
The national on-time rate over the same period is 77.6%, so UA 2350 runs 5 points behind the country as a whole. Across a thousand flights that is about 50 extra late arrivals.

These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 8.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When UA 2350 flies
UA 2350 flies DEN to SYR without a single fixed slot. Its most common scheduled departure was 17:50, used on 54 of 364 flights, with 17:55 (53 flights) and 17:58 (49 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

- Departs 17:5849 flights13.5%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 17:50 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2350 runs 4 points better at 72.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
UA 2350 quarter by quarter
UA 2350 did not run the same all year. Its best quarter was Jan–Mar 2026 at 80.7% on time and its weakest Jul–Sep 2025 at 55.4%, a swing of 25 points on roughly 91 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.

- Oct–Dec 202591 flights76.9%
- Jan–Mar 202690 flights80.7%
- Apr–Jun 202691 flights77.8%
Scale runs 45% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2350 did best on Tuesday at 81.1% on time and worst on Monday at 63.5%. Each day rests on about 52 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2350 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 5,475 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.
- 53%Late-arriving aircraft
- 29%Carrier
- 18%National Airspace System
- 0%Extreme weather
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,475 reported delay minutes here, that single category outweighs weather by 53 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,475 delay minutes reported on UA 2350.
Cancellations are rare at 0.55%, below the national 1.81% 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
8.0% 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 about an hour, which a normal layover absorbs.
The 1,492 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 one other city pair in the data, including RDM to DEN (94), but none flew often enough under UA 2350 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to SYR only.
One caution: this is a thin sample. 364 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 2350
For a booking, read UA 2350 as 72.6% on time with 0.55% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
