I have Half Fare Card which will expire on 2022.02.25 and I would like to buy supersaver ticket for 2022.03.04. Neither in SBB app nor in SBB website (logged in with my account) is reflected the soon expiration, I can’t buy supersaver ticket without half fare discount. Do I need to sign out from the website or app and purchase the ticket or my half fare discount will be valid for the ticket despite the half fare card will be expired at that time? Thanks, Andor
