I intend to buy a ticket from the geneva airport to the ski-resort. The problem is, how you can imagine it’s extremely hard for me to guess my time of arrival due to the usual delays in the flight and bags.
If I buy the normal ticket instead of the supersaver can I then swap them at the train station or just enter whatever train is coming for that destination?
Do the trains usually sell out? Just to know if I should buy in advance or just buy on arrival.
Thank you for your help.
