The problem with bringing another variant on line is it is very restrictive for the flight schedulers, so if you have to switch aircraft you either have too many passengers or empty seats both are a cost. In an ideal word they would have a standard fleet of 800's the 757 fleet seems to be going in one direction and i'm not sure what they would replace it with? I'm sure someone will correct me but have Dart ever bought/leased a new aircraft ?
I guess the main advantage for Jet2 in ALC is it allows for lower frequency to smaller airports without empty positioning costs. Sounds like party time in ALC for Jet2 crews
