Another Bernina question, traveling from Bellagio to a Zurich airport hotel on June 11. My research shows - ferry to Varenna then the 11:24 train to Tirano, wait an hour for the 14:00 Express. My question - Seat 61 advises to buy a ticket from Tirano to Freilburg, de Bahn says I can do this tomorrow to try to get the saver fare. From what I understand I would have to get off in Chur then buy a separate ticket to the airport so the total would run around 70 euros pp. I played around with the Swiss site and I think I can simply buy a ticket from Tirano to the airport for around the same amount of money; am I missing something; also does the Swiss site allow me to book 90 days out like the German site? I even tried the Italian site but it seemed even more confusing.
