SandraI I double check the conditions for “Day Pass for 2” and “Save Day Pass”. It is “a valid Half-Fare travelcard” holder that can purchase “Day Pass for 2” or “Save Day Pass” with reduced price. So it is confused that Swiss Half Fare Card for 1 month isn’t valid for “Day pass for 2”, but is valid for “Save day pass”. If my above understanding is true, I think SBB website should describe these two offers’ condition more accurately. Thank you
