As the subject states, in late September we will be travelling from Varenna-Esino to Tirano in order to catch the Bernina Express.
I notice that I can buy this ticket on the SBB app, which after lots of practice I am starting to become familiar with.
Is this is a good idea or should I stick to buying it on an Italian app such as Trenord? I notice SBB mentions needing to check in before travel. What does that mean?
Final question, I know that most Swiss tickets are for the route not the time, is it the same with this one. If we missed the 14:25 for example, could we simply get the next train or is it different with Italian trains?
Thanks so much in advance.
