Should 'big boned' people pay more to fly?

Then again, if it were a democracy, this idea probably wouldn't fly because there's more fat people than skinny ones in middle america.

What I have seen done though is someone taking out two jackets from their luggage, filling the pockets of both jackets, and then wearing both jackets through security. That seemed to work fine.

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.

There is a plus side though, if you have a family with small kids, the cost of the flight might only come out to be a 2-person cost.

Some friends of mine were stung when they had 25Kg of baggage allowance going out, but the airline changed their policy mid-trip and they were only allowed 20Kg coming back. So they got on the plane wearing their dive gear...

Bird bones are much smaller and less dense than ours. Then you must consider that a bird can already fly, which means that the airplane is not a necessity for them.

In my humble opinion, in light of the prior facts, I do not subscribe to the belief that bone attributes are a reliable means of determining airplane fare.

Or rather, I propose the use of volume, instead.
