Half-Fare PLUS with SBB: when is it worth it?

This year, Switzerland’s SBB railways have introduced a new “Half-Fare PLUS” offer for regular travelers.The principle is simple: you deposit some money upfront and can receive a bonus to use within a year.For example, if you deposit 800 CHF, you obtain a bonus of 200 CHF, meaning that you have 1000 CHF to use within a year.If you don’t use everything when the plan expires, the bonus is lost but anything remaining from the initial deposit is refunded.
