A. Le Rhone & Rook
Just for the record both airlines took a 20% stake in each others airline. This strictly speaking is a partial merger as it was an equity swap. It wasn’t as you imply a one way street. It could just as easily go the other way.
For the record I believe the only fair method of integrating the two bodies is the “Y” shaped method with those employed since the takeover on a common seniority list.
