Yes many times, you can save the extra fee charged by Easyjet and RyanAir.
I use the Visa Elektron which comes optional with the SBB railway half fare card. Before I am planning a trip I transfer money onto the card, this takes an extra day or 2 above the normal Swiss Post Finance transfer time.
You need to be resident in Switzerland to be able to buy Half-Fare travelcard with Visa Card. Start paying with your Half-Fare travelcard: you can now get a combined Half-Fare travelcard and free Visa Card.

The card costs Fr. 125,-- for 12 months
