In reply to COBHC's question regarding aircraft having destination 'names' , it appears Jet2 are slowly moving away from this as the aircraft are rolling out the hangers now in Jet2 Holidays livery.
I'm not sure of why the destination names idea stopped. Maybe because the lettering on the nose was too small for any real marketing value?
I've never heard crews refer to the aircraft by their destination names, just the last letters of thier registrations.
Sometimes fondly changed to names such as 'little princess' for LP, 'always breaking' for AB, 'little 'orrible' for LO and some rather rude ones which I won't write on a public forum but you get the idea!!
