You guys can keep posting statistics until the cows come home, but as long as people keep voting with their wallets, airlines will cram in as many pax as is safe.

Just remember how AA's MRTC crashed and burned.

Airlines are in business of making money, NOT transporting people @:-)

Transporting people is just their way of going about business. Hence the fancy new Polaris seats, which are offered in expectation of attracting customers who also vote with their (much fatter) wallets.
