> "Kirby laid out Delta, United, and Alaska as equally profitable – he adjusts the numbers to get there – American as break-even and then everyone else as money-losing even without recession... > "And he says Spirit Airlines could be going out of business: > [T]he low-cost carriers are just a disaster. These are going-out-of-business numbers for a number of these airlines. You look at Spirit Airlines for example at -30%. That’s a number that is hard to put in context. But if you thought about that at United, if we had a -30% margin, it would mean we actually lose $4.5 billion in a single quarter."
