I'm led to believe this is an RDG requirement, basically the only place you can change an advance to another is with the retailer and that eventually all TOCs and retailers will have to abide by it, we are just the first.
However I understand the customer perspective and love to be able to swap and amend travel plans for people but we are not allowed to unless you go advance to walk up.
If the RDG want to introduce it as a requirement then they should change the conditions of Advance tickets. Advance tickets are totally unregulated, therefore they would be able to do that
tomorrow if they wanted (OK, I appreciate they will have certain notice obligations through contracts they have with retailers and TOCs, but it is certainly possible in a short space of time). Clearly they prefer not only to reduce customers' rights needlessly, but also to fail to inform customers of said reduction in rights. And yet these are the buffoons that want customers to trust them to deliver "easier fares for all". Yeah, right.
I simply don't understand why they think this is necessary. Surely they should be making it
easier to change tickets, e.g. by mandating that TVMs should have this functionality (as some on the continent do). But no, apparently to the RDG, simplification means reducing customer rights.
