Hi, I would like to buy a train ticket from Switzerland to Leipzig. I would like to reserve my seat after another friend has bought the ticket, but SBB assigns you a sit for you, but I would like to sit with my friend. Is there anyway I could buy the train ticket through SBB and reserve the seats later through DB website?
PS. the reason I dont reserve directly through the DB website is because I have a voucher from SBB I would like to use in this purchase
