These figures cover 300 flights between July 2025 and June 2026. Beyond the headline rate, 8.7% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When AS 613 flies

AS 613 flies LAS to SFO without a single fixed slot. Its most common scheduled departure was 07:00, used on 126 of 300 flights, with 08:30 (50 flights) and 06:10 (45 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 AS 613 runs 15 points worse at 74.2%. 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 613 quarter by quarter

AS 613 did not run the same all year. Its best quarter was Jan–Mar 2026 at 90.9% on time and its weakest Apr–Jun 2026 at 26.5%, a swing of 64 points on roughly 75 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, AS 613 did best on Saturday at 91.9% on time and worst on Monday at 65.2%. Each day rests on about 43 flights, so a gap of 27 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 613 runs late

One category carries most of the weight here. National Airspace System accounts for 70% of the 4,517 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.

70% 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 3,146 minutes out of 4,517, against a national NAS share of 21%. The split is drawn from 4,517 delay minutes reported on AS 613.

Cancellations are rare at 0.67%, 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

8.7% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

Every one of the 300 flights under AS 613 in the data flew LAS to SFO. 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. 300 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 613

For a booking, read AS 613 as 74.2% on time with 0.67% cancelled over 300 flights. Those are rates from the past twelve months, not a forecast for any particular day.
