Flying commercial aircraft has never been profitable. We probably only need one airline (one domestic airline at any rate). But most of all, airline prices are vastly too low. Want to fly round-trip New York to DC? Fork over $200.00. Going from California to New York round-trip? That'll be $2,100.00. That's IF we pay the same fares we paid in 1964. See here for example: http://www.jaunted.c...es+Ticket+in+1964
Obviously, the vast majority of Americans won't be flying if we do that. But, (with apologies to Western Airlines) that is the only way to run an airline. The reason the airlines are always facing difficulty is that no one is paying their fair share to fly. We all want to go see Mickey Mouse in Florida for $200.00 per round-trip ticket no matter where we're flying from. It's not possible to do that without MASSIVE amounts of money flying into the airline from somebody. So, either jack your tax rates up and nationalize the industry, or be prepared to pay the piper if you want to continue flying.
