Hello Theckuewhauwh49
When you are about to book the ticket for Italy, you can declare your Swiss Travel Pass as “GA Travel Card”. The STP is the equivalent of the resident’s GA travel card.
Alternatively, you can purchase the ticket for Italy from Chiasso, the border station, while the travel to Chiasso from any Swiss destination is free with your Swiss Travel Pass.
Also, since the STP cannot be added to SBB app, can I print it out or save the pdf format in my phone to show them when there is a check? All I need to do is just to board on any train/ bus within the period, am I right? Please correct me if I’m wrong.
Yes, simply show your ticket as part of a PDF document together with your physical passport. That’s sufficient.
Yes, with the STP you are free to chose any public transport service. It allows travel at will, so you decide to take a train/bus/tram/boat, get on the service, take a free seat, have a ride, and get off where you want. It is using a city transport in other countries, here it works for almost any public transport service.
Kind regards,
Roland
