I just bought a ticket from Vienna to Zurich over Munich via the SBB page. The first part of the trip is operated by ÖBB and I realised that I have an ÖBB Vorteilscard, which should give me some discount. Unfortunately, I was not able to select it in the purchasing process.
Any chance that I can get the discount still (e.g. by contacting customer service? I wasn’t able to add an Austrian discount card in the SBB app).
