UA 1745 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 302 flights, with a median arrival 14 minutes early.

Set against the rest of the country, UA 1745's record is 13 points better than the US average of 77.6%. That gap is worth roughly 126 fewer late arrivals for every thousand flights.

These figures cover 302 flights between July 2025 and June 2026. The median arrival is 14 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 1745 flies

UA 1745 flies DEN to EWR without a single fixed slot. Its most common scheduled departure was 23:59, used on 180 of 302 flights, with 23:54 (86 flights) and 23:50 (36 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 23:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and UA 1745 runs 20 points better at 90.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

UA 1745 next to DEN to EWR

Across the year

UA 1745 quarter by quarter

UA 1745 did not run the same all year. Its best quarter was Oct–Dec 2025 at 96.9% on time and its weakest Jul–Sep 2025 at 75.6%, a swing of 21 points on roughly 76 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.

Oct–Dec 202566 flights96.9%
Jan–Mar 202662 flights94.9%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1745 did best on Wednesday at 95.5% on time and worst on Thursday at 82.9%. Each day rests on about 43 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1745 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 1,861 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.

Late-arriving aircraft
50%
Carrier
38%
National Airspace System
12%

50% 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 1,861 reported delay minutes here, that single category outweighs weather by 50 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 1,861 delay minutes reported on UA 1745.

Cancellations sit at 1.66% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.0% 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.

At 1,605 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on six other city pairs in the data, including SFO to DEN (68), PHX to DEN (56) and SJC to DEN (27), but none flew often enough under UA 1745 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to EWR only.

One caution: this is a thin sample. 302 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 1745
