If you are talking about the collective combination of the bmi pilots and new DEP joiners you are possibly talking about 400 places on the seniority list since time of application and stage one assessment. Plus a move from PP24 to PP34 in this time. Recollecting the recruiters buzz phrases of 'seniority is everything in BA' and 'seniority equals lifestyle,' I can understand where FLR is coming from. Not that it matters now for those in the pool anyway.
Happy Xmas to all my fellow swimmers.
