Just for a little info VirginBlue an Atr 72 is just fractionally more expensive to operate than a 42.Hence Aer Aranns decision to have mainly 72s. The main cost on the Noc route would be overnighting the extra Cabin crew Member.I hope Aerarann get the Noc pso again I can tell you an Atr is alot more comfortable and modern than A Jetstream or a Fokker 50.
