These figures cover 351 flights between September 2025 and August 2026. The median arrival is 10 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.

The worst days
Worst days for AS 1315
The latest arrival of the period was on 8 September 2025, 2 hours 25 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 September 2025 | 2 hours 25 minutes | Late-arriving aircraft |
| 23 February 2026 | 1 hour 42 minutes | Late-arriving aircraft |
| 17 April 2026 | 1 hour 40 minutes | Late-arriving aircraft |
| 12 February 2026 | 1 hour 19 minutes | Late-arriving aircraft |
| 16 April 2026 | 1 hour 17 minutes | Carrier |
Delay causes
Why AS 1315 runs late
Late-arriving aircraft accounts for 74% of the 1,242 delay minutes carriers reported here, and the remaining four split what is left.
- 74%Late-arriving aircraft
- 18%Carrier
- 7%National Airspace System
74% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,242 reported delay minutes here, that single category outweighs weather by 74 to one. The split is drawn from 1,242 delay minutes reported on AS 1315.
Cancellations are rare at 0.57%, 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
Badly late arrivals are rare here: only 2.3% 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 833 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 351 flights under AS 1315 in the data flew LAX 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. 351 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 1315
For a booking, AS 1315 has one of the better records a US domestic flight can show: 91.7% on time and 0.57% cancelled. That is a base rate, not a promise about any single day.
