I think that would be a great idea but it still appeals to the "normal" sized passenger.
Many of these planes are several years old. What is the cost to refurb one and make it fat friendly?
How much would a 50% increase in seat size and row space cost? Or 100%?
What happens if/when fat people make it onto the recognized disabilities list and qualify for ADA?
I think, and I do not know, configuring seats is relatively easy.
It seems to me a typical flight costs somewhere around $15,000 just to break even. If a 737 is seating 130 people at about $250 each, round trip, that's about $16,250 for one leg of a trip. Make a few bucks. Some people pay more, some less, etc, etc and I do not know the cargo dollars and all flights are not 100% full.
So, if we just go with the $16,250 as the goal and make the ticket $150 per leg instead of $125 that is 108 people to make the same dollars, 17% more room. Less sodas, less peanuts, less passenger weight, less baggage weight, more room for other cargo.
The biggest reason I hear is that they make most of their money on business travelers and those people MUST go cheapest most of the time so, comfort is not a consideration.
