Virgin Atlantic Credit Card 2-4-1 voucher useage

[FREEFLIGHTS]

It has always been my understanding that a Virgin Atlantic 2-4-1 voucher could be used on an UC flight from LON to say LAS. A flight from MAN to LAS would also be allowed (that’s if they flew direct these days). However a flight using a 2-4-1 from MAN to LAS via AMS would not be allowed as it is not on Virgin metal.

Is this still a valid rule or is there any evidence/experience of the UC Virgin desk staff allowing some discretion/leway?

Virgin have been very flexible in the way the vouchers can be used but being in Virgin metal is a fixed rule.
