UA 703 lands a B+, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That is a workable record, not a spotless one. That rests on 279 flights, with a median arrival 6 minutes early.

These figures cover 279 flights between July 2025 and June 2026. The median arrival is 6 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 703 flies

UA 703 is scheduled to leave Denver (DEN) at 11:45 local time and reach Billings (BIL) at 13:23. That slot held for 279 of the 279 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 11:45 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 703 runs level with that at 79.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

UA 703 next to DEN to BIL

Across the year

UA 703 quarter by quarter

UA 703 did not run the same all year. Its best quarter was Oct–Dec 2025 at 89.1% on time and its weakest Jan–Mar 2026 at 74.2%, a swing of 15 points on roughly 70 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.

Jan–Mar 202690 flights74.2%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, UA 703 did best on Wednesday at 90.0% on time and worst on Saturday at 72.5%. Each day rests on about 40 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 703 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 2,854 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.

49%
Carrier
32%
National Airspace System
15%
Extreme weather
4%

49% 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 2,854 reported delay minutes here, that single category outweighs weather by 12 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 2,854 delay minutes reported on UA 703.

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

5.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 50 minutes, which a normal layover absorbs.

The same number turns up on six other city pairs in the data, including LAX to DEN (112), MEM to DEN (49) and SDF to DEN (37), but none flew often enough under UA 703 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to BIL only.

One caution: this is a thin sample. 279 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 703

For a booking, read UA 703 as 79.9% on time with 0.00% cancelled over 279 flights. Those are rates from the past twelve months, not a forecast for any particular day.
