These figures cover 284 flights between September 2025 and August 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.

A 07:25 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 718 runs level with that at 87.5%. 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 Apr–Jun 2026 at 92.0% on time and its weakest Jul–Sep 2026 at 79.3%, a swing of 13 points on roughly 71 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 202547 flights84.1%
- Jan–Mar 202673 flights89.0%
- Apr–Jun 202676 flights92.0%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 718 did best on Sunday at 93.0% on time and worst on Tuesday at 80.6%. Each day rests on about 41 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.7% 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.
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. 284 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, read AS 718 as 87.5% on time with 1.76% cancelled over 284 flights. Those are rates from the past twelve months, not a forecast for any particular day.
