These figures cover 360 flights between September 2025 and August 2026. The median arrival is 4 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.

Across the year

AS 756 quarter by quarter

Delay causes

Why AS 756 runs late

Late-arriving aircraft accounts for 58% of the 4,787 delay minutes carriers reported here, and the remaining four split what is left.

58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,787 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 4,787 delay minutes reported on AS 756.

Cancellations are rare at 0.28%, below the national 1.89% 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

7.2% of arrivals land an hour or more late, close to the national 8.3%, so 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.

The 763 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.

Every one of the 360 flights under AS 756 in the data flew LAS to PDX. 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. 360 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 756

For a booking, read AS 756 as 78.3% on time with 0.28% cancelled over 360 flights. Those are rates from the past twelve months, not a forecast for any particular day.
