Exactly why should an executive with Finnair Platinum status owing to long-haul business class flights care about white-collar upper middle-class staffers with Finnair Platinum status owing to intra-Nordic commuting?

They might fly the same short-haul flights, and use the same lounge at Scandinavian capital airports. But other than that, they will use different lounges (HEL premium and intercontinental outstations vs HEL Schengen), different flights and different cabins.

How does the lowly Y flier inconvenience the J flier? I just don't see it. Except for misplaced entitlement and superiority complex, maybe.
