I’m not sympathetic to morbid apron obesity
Too many things to do about it today

But some folks especially men are big folks

Some well muscled fighter or lineman

I know a guy works out with The Mountain

He’s six seven 350

Strength beyond comprehension

Zero fat

Should he pay more

It’s a question u know

This guy can afford forward cabin but those aren’t always there

He should absolutely pay more. Aircraft fuel consumption does not care if you are muscles or fat. Only thing which affects fuel consumption is WEIGHT. To be fair, there should be a surcharge for every pound weight over 100 lbs.

If the passenger is too big to fit in the seat without interfering with adjacent passengers, that passenger needs to pay more for a larger seat. The passenger's weight matters for purposes of weight and balance calculations for the aircraft and impact on fuel consumption.
