UA 1445 lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 307 flights, with a median arrival 13 minutes early.

Set against the rest of the country, UA 1445's record is 6 points better than the US average of 77.6%. That gap is worth roughly 59 fewer late arrivals for every thousand flights.

These figures cover 307 flights between July 2025 and June 2026. The median arrival is 13 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 1445 flies

UA 1445 flies STT to IAD without a single fixed slot. Its most common scheduled departure was 16:45, used on 148 of 307 flights, with 13:02 (125 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 16:45 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 1445 runs 11 points better at 83.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 1445 quarter by quarter

UA 1445 did not run the same all year. Its best quarter was Oct–Dec 2025 at 88.7% on time and its weakest Jan–Mar 2026 at 77.9%, a swing of 11 points on roughly 77 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.

By weekday, UA 1445 ranged from 76.9% on Sunday to 88.0% on Saturday. With about 44 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 1445 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 2,968 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
62%
National Airspace System
19%
Carrier
19%

62% 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 2,968 reported delay minutes here, that single category outweighs weather by 62 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 2,968 delay minutes reported on UA 1445.

Cancellations sit at 1.63% against a national 1.81%, which is ordinary. Diversions add another 1.63%.

Connections and routes

What a delay on this flight costs

6.1% 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 an hour, which a normal layover absorbs.

At 1,606 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.

Every one of the 307 flights under UA 1445 in the data flew STT to IAD. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 307 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.
