UA 1722 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 an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 6 minutes early.

These figures cover 365 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 1722 flies

UA 1722 flies KOA to SFO without a single fixed slot. Its most common scheduled departure was 12:02, used on 53 of 365 flights, with 13:10 (49 flights) and 14:40 (45 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 12:02 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1722 runs level with that at 79.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 1722 quarter by quarter

Quarter by quarter UA 1722 held fairly steady: 81.5% in Jul–Sep 2025, 76.7% in Oct–Dec 2025, 82.6% in Jan–Mar 2026 and 76.4% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights81.5%
Oct–Dec 202592 flights76.7%
Jan–Mar 202690 flights82.6%
Apr–Jun 202691 flights76.4%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1722 did best on Saturday at 85.7% on time and worst on Thursday at 68.6%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1722 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 60% of the 4,319 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
60%
National Airspace System
23%
Carrier
17%

60% 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 4,319 reported delay minutes here, that single category outweighs weather by 60 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 4,319 delay minutes reported on UA 1722.

Cancellations sit at 1.64% against a national 1.81%, which is ordinary. Diversions add another 0.55%.

Connections and routes

What a delay on this flight costs

5.9% 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 2,368 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 four other city pairs in the data, including SFO to MCO (84), SFO to EWR (52) and SFO to PHL (15), but none flew often enough under UA 1722 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to KOA to SFO only.

One caution: this is a thin sample. 365 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.
