It is plain stupidity to keep repeating an ignorant statment that has been explained several times on this board concerning airfares. NWA would have had to raise fares by roughly 15% accross the board in order to break even in 2005. In a pricing environment where there is increasingly more LCC competition on increasingly more routes, it would be financial suicide to go out and raise the price that much (if at all) on a product that is completely price elastic. You do understand that it's better to have 200 people pay $200 dollars on a flight than to have 100 people pay $250, right? That's how supply and demand on airfare pricing works. You optimize revenue on every route you fly, which means pricing the product accordingly.
Simply put, you manage your costs to the level of achiavable revenue for the product you sell, not the other way around (I.E., you can't easily manage your revenue to cover your costs, unless you're a government entity).
I know from your posts that you only have a few things that you say, and it usually is like reading the scattered thoughts of a third grader, but I had to pipe up on this one. I realize you won't understand, either because you can't or because you're too committed to your ignorant view of the world, but it will at least give you and the rest of the "angries" someone else to direct your rage (and economic ignorance) at for a few moments.
