I'm going to Haverfordwest from London, but having to return from Fishguard (due to the unavailability of buses on a Sunday). By chance (i.e. not through any info provided by Arriva Wales) I have come across the concept of inter-available stations which, apparently, allows you to do an "open jaw" return trip, i.e. travel to one station and return from a different one within the same "inter-available" grouping of stations. In my case, Haverfordwest and Fishguard are regarded as inter-available for the purposes of Super Off Peak ticketing.
Questions: how on earth are punters supposed to know about these arcane concepts if no info is available? Does every train operator operate such a policy? Does anyone know of any map that shows these inter-available groupings?
