Ditto - there is a LGW-BGI return in the Easter hols next year for £330 (or about £750 in premium) - these are frankly insane fares, even without seats, luggage and food added. I'd almost be tempted - well with the premium fare anyway - but not if there's an appreciable chance they will be going bust before then.
Am I right in thinking they are still operating transatantic from LGW under fifth freedom rules, so they have to tie flights back to Oslo? Hence the 'government approval' disclaimer...
