We are travelling from Canada to hike the Haute Route. After the hike we plan travel around Switzerland using a Swiss travel pass. Can we transfer the luggage we don't need for the hike from the Geneva airport to the hotel in Zürich where we will be staying at the end of our hike? I've checked the luggage information on the website, and the conditions state:Can I send luggage even if I am not travelling by train?No. You can only check in luggage and flight luggage if you have a valid ticket for the whole transport route or if you hold one of the following annual travelcards: GA Travelcard, Half Fare Travelcard, Point-to-Point Travelcard, Regional Travelcard, FVP (travel discount for SBB employees), seven25 Travelcard, Modular Travelcard.Since we are walking from Chamonix to Zermatt, does that mean the service isn't available for us? Is there an alternative?
