I an cautiously optimistic that PHX won't be hit too hard. I just cannot ignore what happened to LAS.

I am at LAS right now, and I didn't realize how much presence Allegiant and Spirit have over here. US abandoning LAS may not be WN alone but with all the ULCCs. This could happen in PHX. If this happens, I am afraid that PHX could be (1) still a hub/focus city but with more and more RJs (like UA DEN or CLE) or (2) become something like MCO.

I was bummed when LAS was dehubbed. Hope PHX is not hit as hard.
