These figures cover 365 flights between September 2025 and August 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.

Across the year
UA 1722 quarter by 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.

14 of 53 late departures made up the time and arrived on time, 26% of them. In the other direction, 27 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SFO.

Delay causes
Why UA 1722 runs late
Late-arriving aircraft accounts for 50% of the 5,200 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 33%Carrier
- 18%National Airspace System
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,200 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 5,200 delay minutes reported on UA 1722.
Cancellations sit at 2.47% against a national 1.89%, 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 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over 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 (71), SFO to DFW (35) and SFO to EWR (21), 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.
