These figures cover 259 flights between July 2025 and June 2026. The median arrival is 11 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 1107 flies

UA 1107 flies SFO to AUS without a single fixed slot. Its most common scheduled departure was 07:00, used on 182 of 259 flights, with 07:30 (43 flights) and 07:15 (31 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 1107 runs 8 points better at 96.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, UA 1107 ranged from 89.2% on Sunday to 100.0% on Wednesday. With about 37 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 1107 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 438 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.

Late-arriving aircraft
44%
Carrier
29%
National Airspace System
27%

44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 438 reported delay minutes here, that single category outweighs weather by 44 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 438 delay minutes reported on UA 1107.

Cancellations are rare at 0.77%, 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 1.6% 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 1,504 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 ten other city pairs in the data, including CVG to ORD (39), MCO to SFO (19) and AUS to EWR (12), but none flew often enough under UA 1107 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to AUS only.

One caution: this is a thin sample. 259 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 1107

For a booking, UA 1107 has one of the better records a US domestic flight can show: 96.9% on time and 0.77% cancelled. That is a base rate, not a promise about any single day.
