There is almost zero information on PHX. You definitely won’t be able to bid for it by then.

“PHOENIX PILOT BASE

To support Envoy regional flying out of American’s Phoenix Sky Harbor International Airport (PHX) hub, we’re pleased to announce our plans to open a new pilot base at PHX. I know that the next question is when. We anticipate that flying for PHX will begin as early as December of this year. Initially it will be a small amount of flying which we will be able to support through our DFW pilot base, similarly to how we support our Austin (AUS) operation today. However, unlike AUS, PHX flying will continue to grow and we will be opening a system-wide bid for the new pilot base, exact timing yet to be determined.“
