These figures cover 364 flights between July 2025 and June 2026. The median arrival is 12 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 1782 flies
UA 1782 flies BOI to DEN without a single fixed slot. Its most common scheduled departure was 07:00, used on 117 of 364 flights, with 06:15 (111 flights) and 06:30 (62 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 1782 runs 2 points better at 91.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes
Why UA 1782 runs late
One category carries most of the weight here. Carrier accounts for 74% of the 3,574 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.
- 74%Carrier
- 21%National Airspace System
- 5%Late-arriving aircraft
The largest share of delay minutes, 74%, 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 2,633 of the 3,574 delay minutes reported here. The split is drawn from 3,574 delay minutes reported on UA 1782.
Cancellations are rare at 0.82%, 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 3.6% 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 649 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 ORD to CVG (1), but none flew often enough under UA 1782 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOI to DEN 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 1782
For a booking, UA 1782 has one of the better records a US domestic flight can show: 91.7% on time and 0.82% cancelled. That is a base rate, not a promise about any single day.
