These figures cover 364 flights between September 2025 and August 2026. The median arrival is 8 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 1934 quarter by quarter
UA 1934 did not run the same all year. Its best quarter was Oct–Dec 2025 at 91.2% on time and its weakest Apr–Jun 2026 at 72.5%, a swing of 19 points on roughly 91 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 1934 did best on Wednesday at 90.4% on time and worst on Sunday at 70.6%. Each day rests on about 52 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

The worst days
Worst days for UA 1934
The latest arrival of the period was on 30 April 2026, 4 hours 42 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 April 2026 | 4 hours 42 minutes | Late-arriving aircraft |
| 16 March 2026 | 4 hours 19 minutes | Carrier |
| 14 February 2026 | 3 hours 40 minutes | Late-arriving aircraft |
| 13 July 2026 | 3 hours 19 minutes | Late-arriving aircraft |

Delay causes
Why UA 1934 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,758 reported delay minutes.
- 40%Late-arriving aircraft
- 38%Carrier
- 12%National Airspace System
- 10%Extreme weather
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,758 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 3,758 delay minutes reported on UA 1934.
Cancellations are rare at 0.27%, 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
5.0% 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 1,091 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 one other city pair in the data, including AUS to IAH (12), but none flew often enough under UA 1934 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to CLE only.
One caution: this is a thin sample. 364 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 1934
