The lack of experience they are concerned about at LGW is not just down to FPP cadets but also the 737 captains who are all now gradually converting as the airbus takes over SH down there. Not so much experience in total hours but experience on type, they need to avoid a crewing situation where they are left with newly rated airbus skippers flying with new cadets. Anyway, LGW is great as a hideout from LHR but the future is very uncertain.
Times are changing.
