You are talking about the temporary implementation period for bidding onto the 747. Once that period ended it was a free bid using their joint BA seniority. I trained many of these (captains and co-pilots) and they joined the fleet with their BA seniority based on DOJ. The list that I have was sent to everybody when we merged with BCAL. However the ex BEA and ex BOAC pilots are mixed and their position is based purely on DOJ.
