In a few years, after a short period of airline profitability, brought on by lower fuel prices, is crushed by foolhardy union demands, the price of fuel will go up, the cost of flying will rise due to new union contracts and higher fuel prices, and the amortization of the costs of the new jets, so they'll try to boost ticket sales by removing seats. It's almost as if this has happened before. When Frank Borman ran Eastern Airlines, he guessed wrongly that the price of airline fuel was going to remain high, even go higher over time (peak oil nonsense), and "invested" in fuel efficient airframes. Between that wrong move, and the vitriol from the head of one of the unions, Borman was out, and Leastearn Airlines (euphemism) collapsed.
