Bain Capital, LP is in the box seat to succeed in its bid for Virgin Australia Holdings Limited (ASX:VAH) despite union backing for Cyrus Capital Partners, L.P., according to those closest to the bidding process. Virgin Group Holdings Limited, which has stayed close to the administration process, is expected to make its own capital injection in the relaunched airline in return for a 10% stake. Meanwhile, another major player in the process, the bond holders, have brought in Virgin Blue Co-Founder Rob Sherrard as part of a team of 50 people to help with their fight to win control of the airline.
