I saw on these forums that the cheapest option to travel from Zurich to Venice would be to get a ticket via SBB from Zurich to Milan and then get another ticket from Milan to Venice. The cost from Zurich to Milan this way is 85.5 CHF (I have Halbtax).

I noticed that there might be a cheaper option. I can go from Zurich to Chiasso for 35.5 CHF and then take a train from Chiasso to Milan (which I heard is 20 CHF at the trainstation? - http://www.rome2rio.com/s/Chiasso/Milan). Does this seem legit?

A cheaper way would be to go by bus - 70 CHF gets you all the way from Zürich to Venice.

Check out Etihad Regional website. They have direct flight from Geneva to Venice. Price starting from 59 CHF. https://www.etihadregional.com/en-us...y-from-geneva/

Once I went from Zurich to Milano via Chiasso. You can get SBB super saver tickets for Chiasso which would be cheaper than normal ticket but you will have to travel in the train for which ticket was bought. From Chiasso you can buy ticket for Milano and I guess it was less than 6 Euro.

I didn't see the super saver tickets available. When/how are they normally available?

You can book the Italian leg through trenitalia.

* Supersaver tickets may be purchased no more than 14 days before the desired date of travel.
