Hello Moumbafiemb78
As I said: It is available to everyone using the SBB Mobile app. Why should it be mentioned in the app, if it is, in theory, available to all?
If it is offered to you, fine, grab it! What kind of second class ticket do you have in addition?
I said, I am unable to purchase it without a travel card.
When I do a dummy booking for a customer without a travel card, the Supersaver class upgrade disappears. When I do a dummy booking for a customer with a Half Fare Card, the Supersaver offer appears again.
@RedBaron: Can you try it? Can you buy it for a co-passenger without any travel card?
Kind regards,
Roland
