When we went in Jan this year, I managed to get these BA flights for £175 all in!
Real bargain, dedicated group check in (there was 14 of us) really really easy. I know you pay more for lift passes etc if you book independantly, but only a bit.
ellie, ps i know of some accomodation in boro plus i hear the passes and ski packs are going to be as cheap as the tour operators, it only a rumour though lol
