I think someone at Finnair misunderstood what heavy bag perk is about. It is not about plats regularly taking 4x 32kg with them free of charge. It is about "peace of mind". Being loyal and buying expensive fares to not be forced to sweat before every trip. Not bringing a scale to weigh bags and so on.

The message is clear - in the future everyone needs to fret before every Finnair trip, because there will be 'gotchas' at the Airport.

This is similar attitude as airlines that charge for boarding passes. Let's monetize people being human.
