There are a few other operators operating ex SPL (Dutch Bird, Air Holland, Happag NL, Easy Jet). Assuming that they dont have this 56 limit, and they are recruiting.Their market would cover a significant part of the KLM, Martinair,Transavia European segment. That being the case here is a hypothetical; Pilot 56yr gets retired but joins one of the new operators for another 4 years. The growth of these operators is not all new growth, a lot of it comes out of the former majors. Thus their growth is reduced or cut back and therefore junior pilots career path in those majors is slowed down, just as it would be if Pilot 56 yr stayed unill he was 60. So junior pilot has achieved virtually nothing by his objection to extension to 60.
