It is AWAC who decides whether or not AWAC flies for US Airways as I understand it.
Anyway, there is indeed talk of CRJ-900s, at least internally. Nevertheless, this company is famous for keeping secrets so internal rumors really mean nothing.
I will believe it when I see it. But I would not say it won't happen with the same certainty that some others here seem to think.
AWAC will come out of this turbulent period a winner. I am sure of that.
