UA 1378 lands a B+, 3 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 roughly 40 minutes on average.

These figures cover 316 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Schedule

When UA 1378 flies

UA 1378 flies DEN to EGE without a single fixed slot. Its most common scheduled departure was 11:30, used on 67 of 316 flights, with 11:44 (58 flights) and 11:35 (37 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 11:30 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1378 runs level with that at 80.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 1378 quarter by quarter

UA 1378 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.0% on time and its weakest Jan–Mar 2026 at 61.8%, a swing of 31 points on roughly 79 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.

Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1378 did best on Tuesday at 87.0% on time and worst on Sunday at 60.0%. Each day rests on about 45 flights, so a gap of 27 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1378 runs late

One category carries most of the weight here. National Airspace System accounts for 55% of the 2,543 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
21%
Late-arriving aircraft
21%
Extreme weather
4%

55% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,389 minutes out of 2,543, against a national NAS share of 21%. The split is drawn from 2,543 delay minutes reported on UA 1378.

Cancellations are rare at 0.32%, 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 3.5% 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 three other city pairs in the data, including JAC to DEN (49), ATL to DEN (30) and FAR to DEN (6), but none flew often enough under UA 1378 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to EGE only.

One caution: this is a thin sample. 316 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 1378
