These figures cover 350 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.

Schedule

When UA 1768 flies

UA 1768 is scheduled to leave Houston (IAH) at 07:20 local time and reach San Francisco (SFO) at 09:45. That slot held for 293 of the 350 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

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 1768 runs level with that at 89.1%. 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 1768 quarter by quarter

UA 1768 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Apr–Jun 2026 at 79.1%, a swing of 18 points on roughly 70 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 1768 did best on Sunday at 95.8% on time and worst on Saturday at 81.6%. Each day rests on about 50 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Arrival by arrival

How late UA 1768 runs when it is late

UA 1768 often beats the schedule: 114 of 348 completed flights, 33%, arrived 15 minutes or more early. Most of the lateness is short. 26 of the 38 late arrivals were under half an hour behind, and 6 reached an hour or more.

Share of 348 completed flights by arrival against schedule.

A late pushback is often recovered here: of 26 departures that left 15 minutes late or more, 8 still arrived on time. In the other direction, 20 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SFO.

The worst days

The latest arrival of the period was on 17 March 2026, 4 hours 48 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across March, January, June and April, with no single month standing out.

Delay causes

Why UA 1768 runs late

Carrier accounts for 45% of the 1,566 delay minutes carriers reported here, and the remaining four split what is left.

17%

The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 711 of the 1,566 delay minutes reported here. The split is drawn from 1,566 delay minutes reported on UA 1768.

Cancellations are rare at 0.57%, 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

Badly late arrivals are rare here: only 1.7% land an hour or more behind schedule, against 8.3% 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 1,635 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.

The same number turns up on one other city pair in the data, including SFO to BUR (79), but none flew often enough under UA 1768 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to SFO only.

One caution: this is a thin sample. 350 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 1768

For a booking, UA 1768 has one of the better records a US domestic flight can show: 89.1% on time and 0.57% cancelled. That is a base rate, not a promise about any single day.
