How does the BahnCard 25 or 50 accompanying-person special offer work?

The BahnCard 25 or 50 holder adds a second passenger during the booking process. They must also specify the BahnCard 25 or 50 discount and the same travel class for this person. The accompanying person receives the same discounts as the holder of the BahnCard 25 or 50, without needing their own discount card. Both passengers must be booked on one ticket.
