The worst days
Worst days for AS 1302
The latest arrival of the period was on 6 March 2026, 7 hours 6 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 7 hours 6 minutes | Carrier |
| 9 August 2026 | 6 hours 1 minute | Late-arriving aircraft |
| 1 May 2026 | 4 hours 57 minutes | Carrier |
| 13 March 2026 | 3 hours 47 minutes | Late-arriving aircraft |
| 3 January 2026 | 2 hours 51 minutes | Carrier |
Delay causes
Why AS 1302 runs late
Late-arriving aircraft accounts for 63% of the 5,353 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Late-arriving aircraft
- 27%Carrier
- 10%National Airspace System
63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,353 reported delay minutes here, that single category outweighs weather by 63 to one. The split is drawn from 5,353 delay minutes reported on AS 1302.
Cancellations are rare at 0.62%, 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
8.4% 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 550 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 324 flights under AS 1302 in the data flew SFO 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. 324 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.
