These figures cover 338 flights between July 2025 and June 2026. The median arrival is 15 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 2316 flies
UA 2316 flies DEN to LAS without a single fixed slot. Its most common scheduled departure was 07:45, used on 190 of 338 flights, with 08:05 (60 flights) and 08:00 (52 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 07:45 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2316 runs 5 points better at 93.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
UA 2316 quarter by quarter
Quarter by quarter UA 2316 held fairly steady: 93.9% in Jul–Sep 2025, 94.5% in Oct–Dec 2025, 92.2% in Jan–Mar 2026 and 94.5% in Apr–Jun 2026. A spread of 2 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202566 flights93.9%
- Oct–Dec 202591 flights94.5%
- Jan–Mar 202690 flights92.2%
- Apr–Jun 202691 flights94.5%
Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2316 ranged from 91.7% on Thursday to 97.9% on Friday. With about 48 flights behind each day, a spread of 6 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why UA 2316 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 1,116 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.
- 46%Late-arriving aircraft
- 35%National Airspace System
- 19%Carrier
46% 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 1,116 reported delay minutes here, that single category outweighs weather by 46 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 1,116 delay minutes reported on UA 2316.
Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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 2.1% 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 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 five other city pairs in the data, including LAS to LAX (94), LAS to EWR (63) and LAS to ORD (36), but none flew often enough under UA 2316 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to LAS only.
One caution: this is a thin sample. 338 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 2316
For a booking, UA 2316 has one of the better records a US domestic flight can show: 93.8% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
