Swiss Transfer Ticket
Does anyone know where to find the detailed written rules on this? (I've looked on sbb.ch and also their more tourist 'swisstravelsystem.com' sites, but I can't find them)
Do they require proof of your travel dates (boarding passes, etc)? Or just that you are a visitor (residence document from outside switzerland)?
Basically, are you fine to use it a few days after you arrive - journey would still depart from an airport station?
(I assuming returning to the airport the night before flight is not a problem, it was more having a few days before you start using it).
