Apologies if I missed something, but searching for some flights and started playing around with searching with the "GPU upgrade use" function...mostly because search by fare class seems to not be working.

Search results are showing economy fares that are "premium economy up-gradable", including available instead of wait-listed data. (Also continues to list them as business cabin up-gradable).

Is this a new thing? Does a GPU confirm directly to Premium Economy for fares under W?

Not sure if related, but also noticed that 777-200 seat maps seem to be unavailable for both existing and new bookings.
