These figures cover 342 flights between September 2025 and August 2026. The median arrival is 2 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 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 2026 at 60.0%, a swing of 21 points on roughly 68 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.

Share of 339 completed flights by arrival against schedule.
18 of 78 late departures made up the time and arrived on time, 23% of them. In the other direction, 25 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SYR.
The worst days
Worst days for UA 2350
The latest arrival of the period was on 24 July 2026, 3 hours 27 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 July 2026 | 3 hours 27 minutes | Late-arriving aircraft |
| 3 July 2026 | 3 hours 14 minutes | Late-arriving aircraft |
| 7 September 2025 | 3 hours 10 minutes | Late-arriving aircraft |

Delay causes
Why UA 2350 runs late
Late-arriving aircraft accounts for 64% of the 4,674 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Late-arriving aircraft
- 18%Carrier
- 17%National Airspace System
- 1%Extreme weather
64% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,674 reported delay minutes here, that single category outweighs weather by 64 to one. The split is drawn from 4,674 delay minutes reported on UA 2350.
Cancellations are rare at 0.58%, below the national 1.89% 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
7.4% 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 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.
The same number turns up on one other city pair in the data, including RDM to DEN (155), 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. 342 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 74.9% on time with 0.58% cancelled over 342 flights. Those are rates from the past twelve months, not a forecast for any particular day.
