This is not going to work. #PassengerPackage
There is a SINGLE TRANSACTION obligation to get rights - see https://transport.ec.europa.eu/document/download/fc019827-59c9-400f-a530-4d7d21957a7d_en?filename=COM_2026_233_Proposal_on_the_protection_of_passengers_with_single_tickets.pdf
BUT that means that IF you have some ticket already - a Klimaticket for example - and want to add something on to that, you are left without rights
