Few days ago I wrote email to USAirways HQ. I've asked them about USAirways Shuttle (because I'm flying them very frequently), about DC Air and United Airlines. Here is complete email I got from them:
"Dear Mr. Szczypek,
We can appreciate your concern. Until all policies and provisions have been addressed and agreed upon,
we are operating business as usual. We do not anticipate an approval of this merger prior to first quarter 2001 at the very earliest. All existing US Airways bookings/tickets will be honored after the merger. You have no cause for concern.
You are a valued customer and we look forward to welcoming you aboard our flights, no matter what the name on the door.
No matter what the NAME on the door. haha they dont know or they dont want to tell us who will takeover USAirways Shuttle.
