These figures cover 267 flights between July 2025 and June 2026. The median arrival is 5 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 595 flies
UA 595 flies AUS to DEN without a single fixed slot. Its most common scheduled departure was 09:00, used on 87 of 267 flights, with 08:52 (49 flights) and 08:50 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

- Departs 08:5037 flights13.9%

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 595 runs 3 points better at 86.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
UA 595 quarter by quarter
UA 595 did not run the same all year. Its best quarter was Apr–Jun 2026 at 92.7% on time and its weakest Jul–Sep 2025 at 81.3%, a swing of 11 points on roughly 67 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.
- Jul–Sep 202592 flights81.3%
- Oct–Dec 202592 flights90.2%
- Jan–Mar 202642 flights84.6%
- Apr–Jun 202641 flights92.7%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 595 ranged from 81.6% on Wednesday to 91.9% on Monday. With about 38 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why UA 595 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 1,606 reported delay minutes.
- 40%Carrier
- 33%National Airspace System
- 27%Late-arriving aircraft
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 646 of the 1,606 delay minutes reported here. The split is drawn from 1,606 delay minutes reported on UA 595.
Cancellations sit at 1.50% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.3% land an hour or more behind schedule, against 8.1% 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.
The 775 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on three other city pairs in the data, including DCA to ORD (53), EWR to IAH (24) and DEN to EWR (21), but none flew often enough under UA 595 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to AUS to DEN only.
One caution: this is a thin sample. 267 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
