Regarding easyjet, many of you need to realise that whilst w patterns/out of base flying can raise challenges, the actual nightstopping of crew I'd not one of them. Productivity wise, the crew won't lose hours by nightstopping (infact in theory they can reduce rest period) and still operate as much as they would in base over the same period. Also, nightstopping crews is not that expensive on the scheme of things. Airlines have very preferential hotel contracts and ezy has some nightstops across the network already in addition to nightstops associated with out of base flying and training.
