UA 2063 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 11 points better than the national rate of 77.6%.

These figures cover 271 flights between July 2025 and June 2026. The median arrival is 11 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 2063 flies
UA 2063 flies BZN to DEN without a single fixed slot. Its most common scheduled departure was 07:00, used on 117 of 271 flights, with 06:15 (55 flights) and 06:30 (46 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2063 runs level with that at 88.8%. 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 2063 next to BZN to DEN

Across the year
UA 2063 quarter by quarter
UA 2063 did not run the same all year. Its best quarter was Apr–Jun 2026 at 96.0% on time and its weakest Oct–Dec 2025 at 78.4%, a swing of 18 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.

- Oct–Dec 202539 flights78.4%
- Jan–Mar 202690 flights92.2%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2063 did best on Tuesday at 94.9% on time and worst on Saturday at 76.3%. Each day rests on about 39 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2063 runs late
One category carries most of the weight here. National Airspace System accounts for 43% of the 2,039 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.
- 43%National Airspace System
- 33%Extreme weather
- 20%Carrier
- 4%Late-arriving aircraft
Extreme weather accounts for 33% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 5.3 times the usual weather exposure. The split is drawn from 2,039 delay minutes reported on UA 2063.
Cancellations are rare at 0.37%, 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 2.6% 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 524 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 three other city pairs in the data, including DEN to SAT (53), ORD to BNA (41) and SAT to IAH (16), but none flew often enough under UA 2063 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BZN to DEN only.
One caution: this is a thin sample. 271 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 2063
For a booking, UA 2063 has one of the better records a US domestic flight can show: 88.8% on time and 0.37% cancelled. That is a base rate, not a promise about any single day.
