I thought I bought a bus ticket Geneva airport-> Annecy. The website says that the bus departing 16:00 is nonstop. But my ticket is confusing. It says "from Lancy-Bachet, gare". It also says "your choice: Geneve-Aeroport, gare routiere via Lancy-Bachet, gare". Where and when do I board the bus? At the Airport? at Gare-routiere in town? Do I have to take a train to Lancy-Bachet? Does the bus leave the airport at 16:00 or Lancy Bachet at 16:00? Thank you for advice
