According to USAviation.com the deal was completed today.
"We have been advised by Captain Lyle Hogg that the sell transaction between Republic and MDA is complete. Classes at Republic to resume on September 27. He states that a new pref. sheet will be sent out shortly. This just posted in Sabre Crew Trac."
Good luck to the fine people at MDA. They have been tossed around, used, and discarded time and again -- pawns in some kind of management chess game. They deserve much, much better.
