AS likely has that aircraft repurposed to a more profitable route.
Somehow I doubt AS is really losing the SJC-PDX market to people booking SJC-PHX-PDX or SJC-LAX-PDX.
Yes generally "the airline had more profitable use elsewhere" is a reasonable answer to most scheduling decisions but this one is questionable for the reasons I mentioned. They have plenty of other dubious routes out of SJC and SFO; an evening SJC-PDX flight is not one of those. It seems like basic, essential route if you have a hub at PDX and a focus city at SJC.
[side note as an OAK partisan it is nice to see a seemingly irrational decision to not offer some basic service at SJC when it's always the opposite]
