Should you really penalize people because of their genetics? You're already rewarded based on your genetics. (You can afford to fly more if you're genetically smart, and not, say, genetically a squirrel.) And since weight imposes a cost, it's just a question of whether that cost is borne by the people who cause it (heavy people who choose to fly) or by everyone.
