I was told the bases on offer were Man,Ema,Ncl
I'm surprised you were told EMA places were on offer to new entrants??
There are quite a lot of names on the base transfer list and as I understand it, it will be done on seniority (which, too be honest, is how everything ought to be done in Jet2 now growth has dropped off and there are many SFO's who are appraching or have attained command hours).
Although having some more wide bodied, ETOP's experienced guys is highly needed if J2 eventually start doing more 'pond-hopping' routes.
