Rainboe - exactly! As I mentioned earlier, if BA had their way, they would probably not use EU pilots but US pilots.
Starting routes to different EU cities all served from JFK or EWR, why would you choose EU pilots with multi base inefficiencies? Choosing JFK/EWR based pilots would be much more robust, and it is only a question of providing hotac in BRU/CDG/FRA vs NYC!
BALPA's task is to try to find a way of retaining these jobs for BA pilots operating rotations ex LHR.
