As is always the way with jet2. There is a cost implication. I.e. There is a cost to do it. Nothing works here unless it's for peanuts or free. The crews who do work are the peanut type. Cabin get no sales bonus now really. Flight getting sick of the rubbish. The 757 are short of crew so doubt they could fly further afield on a 767. As with ppjn they are onto bigger better things such as 707 ha ha.
