These figures cover 359 flights between July 2025 and June 2026. The median arrival is 16 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 372 flies

UA 372 flies BIL to DEN without a single fixed slot. Its most common scheduled departure was 07:00, used on 256 of 359 flights, with 06:30 (60 flights) and 06:35 (40 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 372 runs level with that at 90.8%. 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 372 runs late

One category carries most of the weight here. Carrier accounts for 57% of the 2,783 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.

Carrier
57%
Late-arriving aircraft
19%
National Airspace System
13%
Extreme weather
11%

Extreme weather accounts for 11% 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 1.8 times the usual weather exposure. The split is drawn from 2,783 delay minutes reported on UA 372.

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 3.1% 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 same number turns up on six other city pairs in the data, including DEN to PWM (35), DEN to SRQ (25) and DEN to PBI (24), but none flew often enough under UA 372 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BIL to DEN only.

One caution: this is a thin sample. 359 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 372

For a booking, UA 372 has one of the better records a US domestic flight can show: 90.8% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
