UA 2483 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 303 flights, with a median arrival 6 minutes early.

These figures cover 303 flights between July 2025 and June 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.

Schedule

When UA 2483 flies

UA 2483 is scheduled to leave Houston (IAH) at 14:20 local time and reach Austin (AUS) at 15:22. That slot held for 300 of the 303 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 14:20 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 2483 runs 8 points better at 80.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

UA 2483 next to IAH to AUS

Every carrier on IAH to AUS combined arrived on time 79.4% of the time across 2,675 flights, so UA 2483 is about level with it. United flew 2,609 flights on the same city pair under all its flight numbers, including this one, and those ran 79.4% on time. Across its whole network United Airlines managed 79.0%, close to this flight's figure.

Across the year

UA 2483 quarter by quarter

UA 2483 did not run the same all year. Its best quarter was Jan–Mar 2026 at 91.0% on time and its weakest Jul–Sep 2025 at 70.8%, a swing of 20 points on roughly 76 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 202589 flights70.8%
Oct–Dec 202586 flights82.6%
Jan–Mar 202680 flights91.0%
Apr–Jun 202648 flights77.1%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, UA 2483 did best on Thursday at 84.8% on time and worst on Sunday at 69.0%. Each day rests on about 43 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2483 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 4,243 reported delay minutes.

National Airspace System
37%
Carrier
30%
Late-arriving aircraft
22%
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 4,243 delay minutes reported on UA 2483.

Cancellations are rare at 0.66%, 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

7.3% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

The same number turns up on seven other city pairs in the data, including ORD to IAH (170), ROC to ORD (169) and ORD to EUG (41), but none flew often enough under UA 2483 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to AUS only.

One caution: this is a thin sample. 303 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 2483
