Certainly, good and welcome news, but I'd be a lot happier if BE were to go the whole way and offer through check in (and fares) with Froggy-Baby to various worldwide destinations; the real importance of the new CDG route is that it gives JER intercontinental travellers the opportunity to interline directly onto worldwide routes without having to go via LGW/LHR and that awful coach service. Although it's outside their current operating method, the transiting/connecting pax could provide sufficient extra traffic to sustain the flights and build frequency - why throw that business away?
Don't they still have interline agreements with CO,VS etc. via LGW anyway?
