Note that in order to purchase a BE fare, there is a dual-inventory check. There must be both inventory in X and the underlying coach fare basis bucket for the BE fare.
Well it appears that V is the old K so you can use a GGU with it providing there is U space.....

Zeroed buckets and higher fares are likely fared to discourage sales during the shift, especially when the flights are place holders that far out. No need to book fares for the fall right now. It is akin to shooting at a moving target.
If AS has same-day walk-up Main fares PHX-SEA for $74 I don't see a need to book fall travel until late summer. Everything should be synced & ironed by then.
