These figures cover 266 flights between September 2025 and August 2026. The median arrival is 7 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 25 December 2025 | 6 hours 48 minutes | Late-arriving aircraft |
| 6 July 2026 | 4 hours 33 minutes | Late-arriving aircraft |
| 17 July 2026 | 2 hours 50 minutes | Late-arriving aircraft |

Delay causes
Why UA 2332 runs late
Late-arriving aircraft accounts for 63% of the 2,445 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Late-arriving aircraft
- 22%Carrier
- 14%National Airspace System
63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,445 reported delay minutes here, that single category outweighs weather by 63 to one. The split is drawn from 2,445 delay minutes reported on UA 2332.
Cancellations are rare at 0.38%, below the national 1.89% 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 4.5% land an hour or more behind schedule, against 8.3% 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 1,504 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 eight other city pairs in the data, including PDX to SFO (65), IAH to DCA (35) and ONT to SFO (24), but none flew often enough under UA 2332 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to AUS only.
One caution: this is a thin sample. 266 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 2332
