What about the scenario of a Plat with e.g. XXX-HEL-XXX and the person being upgraded for 50K round trip has HEL-XXX-HEL with both flying HEL-XXX on the same day, would the companion benefit from this? Or does the entire itinerary be the exact same dates and departure points for the long haul segment (subject to availabilty)?
I assume this would be a case of HUACA
