These figures cover 280 flights between July 2025 and June 2026. The median arrival is 17 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 F9 1267 flies
F9 1267 flies SLC to LAX without a single fixed slot. Its most common scheduled departure was 10:15, used on 35 of 280 flights. 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 10:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and F9 1267 runs 4 points better at 88.4%. 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
F9 1267 quarter by quarter
F9 1267 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.7% on time and its weakest Jul–Sep 2025 at 74.5%, a swing of 21 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.

- Oct–Dec 202578 flights88.5%
- Jan–Mar 202675 flights92.0%

By weekday, F9 1267 did best on Saturday at 94.6% on time and worst on Thursday at 80.9%. Each day rests on about 40 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 1267 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 2,238 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.
- 50%Late-arriving aircraft
- 34%Carrier
- 16%National Airspace System
50% 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 2,238 reported delay minutes here, that single category outweighs weather by 50 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 2,238 delay minutes reported on F9 1267.
Cancellations sit at 1.07% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.3% 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 590 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.
Every one of the 280 flights under F9 1267 in the data flew SLC to LAX. 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. 280 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 F9 1267
For a booking, F9 1267 has one of the better records a US domestic flight can show: 88.4% on time and 1.07% cancelled. That is a base rate, not a promise about any single day.
