Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1934, check with United Airlines.

UA 1934 earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 364 flights, with a median arrival 9 minutes early.

Set against the rest of the country, UA 1934's record is 7 points better than the US average of 77.6%. That gap is worth roughly 69 fewer late arrivals for every thousand flights.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 9 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 1934 flies

UA 1934 flies IAH to CLE without a single fixed slot. Its most common scheduled departure was 07:20, used on 132 of 364 flights, with 18:05 (92 flights) and 14:35 (40 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 07:20 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 1934 runs 5 points worse at 84.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

UA 1934 next to IAH to CLE

Every carrier on IAH to CLE combined arrived on time 84.3% of the time across 824 flights, so UA 1934 is about level with it. Across its whole network United Airlines managed 79.0%, which this flight beats by 6 points.

Across the year

UA 1934 quarter by quarter

UA 1934 did not run the same all year. Its best quarter was Jul–Sep 2025 at 92.3% on time and its weakest Apr–Jun 2026 at 72.5%, a swing of 20 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.

Jul–Sep 202592 flights92.3%
Oct–Dec 202591 flights91.2%
Jan–Mar 202690 flights82.0%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1934 did best on Friday at 90.2% on time and worst on Sunday at 76.5%. Each day rests on about 52 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

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 3,246 reported delay minutes.

Late-arriving aircraft
37%
Carrier
37%
National Airspace System
14%
Extreme weather
12%

Extreme weather accounts for 12% 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 1.9 times the usual weather exposure. The split is drawn from 3,246 delay minutes reported on UA 1934.

Cancellations are rare at 0.27%, below the national 1.81% 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 4.4% 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 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. 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 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

For a booking, read UA 1934 as 84.5% on time with 0.27% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
