When you say "for both", what are you referring to?
There is a footnote 2, which says pajamas are available on all flights to Asia and other longish flights. While we can't see the text where footnote 2 appears, as of last week still no pjs on Japan flights from the West Coast or Denver.
This may reduce Polaris overcrowding depending on the price differential. I also think it is fairer for people who book at the last minute, typically pay more, but then get a lousy seat assignment.
Thanks for posting OP!
