America West Express will upgrade all flights in September out of OKC to CRJ-900s; the 90-seaters. This will gear up for the merger with US Airways which will take place on September 15th. The airline will then operate as US Airways from that point forward. Current indications are that half of the existing CRJ-900 fleet will be moved to the existing US Airways network, likely out of Charlotte. I would expect announcements later in the summer for new service to Charlotte to be announced and then later Philadelphia.

I'll get the full schedule loaded for HP/US, and everyone else, loaded over on USAFlying.com in the OKC section sometime tomorrow.
