I just received the joint XL and BALPA statement in the post this morning. I'm 737 fleet, but wondered how secure my position is. Obviously the pilot reduction is coming from the withdrawal of 767/757 and 747, but it does state in the letter that those affected on those fleet types will be asked to state a non-binding preference for type, base or future. What does this mean? Does it imply that if a 75/76 driver who came from the 737 and has more seniority than other current crews on the 737 fleet, then he/she is in and the less senior is out the door? Any informed views would be appreciated.
