What I've never understood about Air-Scotland is their use of the Boeing 757-200 other than that they may have been available at the time of launch. I realise that this airline is technically a charter airline, however, by marketing themselves as a no-frills airline, they ought to have at least some no-frills qualities like at least daily flights to destinations, fast turnarounds etc.
I remember when discussing aircraft types with some people at MYT before I left, that the 757 cannot be turned any quicker than 50 minutes. Quite a long way from Ryanair's 25-min turn.
