Triv what is the exact problem with Grenoble airport.Nothing really.Land -}straight transfer-}ski( a hell of a number of resorts big and small) and back --easy.
Apart from being pathetically small (considering the volume of flights coming into and out of Grenoble), the baggage collection organisation was disasterous. The screens were not used, no one knew which conveyor belt to collect your luggage from, was overcrowded and just crap!
