UA 1192 lands a B+, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average.

These figures cover 365 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 1192 flies

UA 1192 flies IAH to SJU without a single fixed slot. Its most common scheduled departure was 10:10, used on 154 of 365 flights, with 10:03 (94 flights) and 10:07 (68 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 10:10 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 1192 runs 8 points worse at 76.6%. 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 1192 quarter by quarter

UA 1192 did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.4% on time and its weakest Jul–Sep 2025 at 69.6%, a swing of 13 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 1192 did best on Tuesday at 88.7% on time and worst on Saturday at 54.9%. Each day rests on about 52 flights, so a gap of 34 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1192 runs late

One category carries most of the weight here. National Airspace System accounts for 46% of the 3,635 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier

Late-arriving aircraft

Extreme weather
3%

46% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,672 minutes out of 3,635, against a national NAS share of 21%. The split is drawn from 3,635 delay minutes reported on UA 1192.

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 4.1% 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.

At 2,007 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

Every one of the 365 flights under UA 1192 in the data flew IAH to SJU. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 365 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.
