The service will be a sucess but due to lack of resources(not that there is) they cant continue and infact sell the route/slots to someone like CO who will operate the service 5-6 weekly code-sharing with LS!!!
There is nothing to sell. There is no route authority and as yet no slots at EWR
And why CO would be interested in codesharing with Jet 2 I have no idea when CO could make a LBA route work themselves. However with current fuel prices and cutbacks CO are not going to be intersted in LBA for a long while I would expect
