Can I get a 50% discount on rail tickets I’ve already purchased with a rail card?
I am a temporary visitor to Switzerland (but my office is here, so I will come several times a year). Yesterday I needed to buy 200CHF worth of tickets. Obviously a rail card would be helpful, but it takes 10 days to issue, which I don’t have time for. If I purchase a rail card, am I able to retrospectively claim 50% off full fare tickets I have already bought? Even as credit for future trips?
