These figures cover 327 flights between July 2025 and June 2026. The median arrival is 13 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 2185 flies
UA 2185 is scheduled to leave Medford (MFR) at 05:00 local time and reach Denver (DEN) at 08:33. That slot held for 306 of the 327 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 05:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2185 runs 3 points better at 92.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route
UA 2185 next to MFR to DEN

Across the year
UA 2185 quarter by quarter
UA 2185 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.8% on time and its weakest Oct–Dec 2025 at 86.7%, a swing of 11 points on roughly 82 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.
- Jul–Sep 202592 flights97.8%
- Oct–Dec 202591 flights86.7%
- Jan–Mar 202653 flights90.6%
- Apr–Jun 202691 flights92.2%
Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2185 did best on Thursday at 100.0% on time and worst on Monday at 86.7%. Each day rests on about 47 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2185 runs late
One category carries most of the weight here. Carrier accounts for 91% of the 4,359 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.
- 91%Carrier
- 4%Late-arriving aircraft
- 4%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 91%, 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 3,964 of the 4,359 delay minutes reported here. The split is drawn from 4,359 delay minutes reported on UA 2185.
Cancellations are rare at 0.31%, 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
Badly late arrivals are rare here: only 3.7% 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 964 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 four other city pairs in the data, including DEN to PNS (118), DEN to TPA (49) and DEN to SYR (37), but none flew often enough under UA 2185 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MFR to DEN only.
One caution: this is a thin sample. 327 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 2185
For a booking, UA 2185 has one of the better records a US domestic flight can show: 92.0% on time and 0.31% cancelled. That is a base rate, not a promise about any single day.
