Historical statistics for July 2025 to June 2026, not live status. For today’s AS 718, check with Alaska Airlines.

AS 718 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 288 flights, with a median arrival 11 minutes early.

Set against the rest of the country, AS 718's record is 14 points better than the US average of 77.6%. That gap is worth roughly 138 fewer late arrivals for every thousand flights.

These figures cover 288 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 AS 718 flies

AS 718 flies SFO to LAS without a single fixed slot. Its most common scheduled departure was 08:50, used on 50 of 288 flights, with 07:20 (46 flights) and 08:48 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 07:2046 flights16.0%
  • Departs 08:4845 flights15.6%

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

A 08:50 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 718 runs 7 points better at 91.4%. 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

AS 718 quarter by quarter

AS 718 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.6% on time and its weakest Oct–Dec 2025 at 84.1%, a swing of 13 points on roughly 72 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 202592 flights96.6%
  • Oct–Dec 202547 flights84.1%
  • Jan–Mar 202673 flights89.0%
  • Apr–Jun 202676 flights92.0%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, AS 718 ranged from 88.6% on Monday to 95.6% on Sunday. With about 41 flights behind each day, a spread of 7 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AS 718 runs late

One category carries most of the weight here. Carrier accounts for 75% of the 1,685 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
    75%
  • National Airspace System
    19%
  • Late-arriving aircraft
    6%

The largest share of delay minutes, 75%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,265 of the 1,685 delay minutes reported here. The split is drawn from 1,685 delay minutes reported on AS 718.

Cancellations run at 2.78%, against 1.81% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

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 same number turns up on one other city pair in the data, including LAS to SFO (67), but none flew often enough under AS 718 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to LAS only.

One caution: this is a thin sample. 288 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 AS 718

For a booking, the cancellation rate is the figure to plan around on AS 718: 2.78% of its 288 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
