ashmac,
Not for Jet2 but otherwise yes, if you catch my drift.
Aye, LBA-LGW would be a real feather in Jet2's cap but it would need some pretty heavy advertising (which they seem to excel at), especially in the southeast coz as 682 points out, Jet2 are virtually unknown down there. Maybe that's a good thing, no preconceptions and coloured judgments about locos in general.
