while its not a final name for such a commodity, i wouldn t use "zoner passenger" - but rather something like zoner emigrant or so. - to make clear that most of those people only book "one way tickets".
anyway - i d lean towards option b, too. ( both parts - origin / destination ) - imo - a "fresh" zoner would probably flee to one of the borderstations ( like fp2, 6 or 1 ) - and only from there - after some time... they d go further into the edgeworlds.
i don t see emigrants from the core to go straight to fp11 or 10.
