Well interesting move by Jet2 if its going to happen. Strange though that they would want to market a premium-only service when their core brand is "the Low Cost Airline". In my opinion not many business or premium-leisure passengers would ever associate the name Jet2 with premium travel so its going to take a lot of convincing to win over the type of passenger it would want to attract for this new venture.
Lets hope they re-brand this proposed premium part of the business or it could all fall flat on its face.
Just my opinion
