Raise the prices. The airlines need it.
The traveling public needs to realize that even paying $100-$200 more per flight is still a bargain compared to how much it would cost them to drive the same trip (longer trips of course).
I find it amazing that what airlines we have left have managed to stay afloat with the low ticket prices that some have been charging. Maybe I'm biased because I can appreciate a little better the hard work and training that goes into safely hurling 200 people across the country in a metal tube 6 miles above the Earth, than the majority of people who take that feat for granted every single day.
Their $78 contribution to an airline gets them 1500nm away from where they started.
I imagine the GA guys are likely to agree these days, as well. You can't fly an archer on even a 400nm trip for less than maybe $600-$700 (rental + gas) I figure. So being *forced* to pay that much to travel several thousand miles in the safety and comfort of an airliner is a STEAL.
