The 150% PQM P fares isn't great, but lately it has mostly been Z fares for me, so it will be interesting to see how it plays out.
I think the $15k requirement isn't great, especially with a downgrade in RPUs (even though they aren't really all that usable).
What matters is how they implement this true Prem Plus class. If it is a modest price difference internationally but gives you a guaranteed GPU upgrade to biz, then I will likely be happy. But if it's a significant price delta with the same GPU lottery that we have today to get into biz, I am much less likely to bite.
