These figures cover 307 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 622 quarter by quarter
UA 622 did not run the same all year. Its best quarter was Oct–Dec 2025 at 83.1% on time and its weakest Jul–Sep 2026 at 72.9%, a swing of 10 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 622 did best on Saturday at 95.1% on time and worst on Sunday at 66.7%. Each day rests on about 44 flights, so a gap of 28 points is worth noticing but could still narrow in another year.
Arrival by arrival

Share of 302 completed flights by arrival against schedule.
14 of 61 late departures made up the time and arrived on time, 23% of them. In the other direction, 19 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 AUS.

|---|---|---|
| 7 June 2026 | 6 hours 1 minute | Extreme weather |
| 7 December 2025 | 5 hours 24 minutes | Late-arriving aircraft |

Delay causes
Why UA 622 runs late
Late-arriving aircraft accounts for 46% of the 4,475 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 22%National Airspace System
- 17%Carrier
- 15%Extreme weather
Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.5 times the usual weather exposure. The split is drawn from 4,475 delay minutes reported on UA 622.
Cancellations sit at 1.30% against a national 1.89%, which is ordinary. Diversions add another 0.33%.
Connections and routes
What a delay on this flight costs
7.0% 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 about an hour, which a normal layover absorbs.
The 977 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on eight other city pairs in the data, including CMH to ORD (123), PHL to ORD (108) and LGA to ORD (35), but none flew often enough under UA 622 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to AUS only.
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.
What to do with this
Booking UA 622
