Routing rules all say these are V basis even if the booking class is different. Looks like this is a Y-up fare. Lowest booking class I can find into First is K.

Even though P bucket is available on 5/21 (searching ANC-SEA), I'm not seeing a P fare filed. I thought they were filed as their own fares previously? Searching for Booking Class: P returns only these Y-up fares and the booking class is not P.

How are these handled for IRROPs/downgrades? Do they get AL access? What other asterisks are behind these? I know it's a little early to have answers.
