I remember they used to say the same thing decades ago about automobiles. People would only pay so much for gas before they would stop using their cars as a means to get from point A to point B. Problem was they offered up no other viable mode of transportation to replace their car if this happened. Same thing with air travel now. We have made it so convenient for the travelling public to fly from point A to point B that, really, what other alternative is out there for them if ticket prices rise? Greyhound? Amtrak? Hop in the family truckster and pay 3 times as much and spend 5 times as long to get to the same place? I think its an antiquated philosophy thinking that folks won't pay more. They have become so used to easy air travel that they have no alternative. They still need to travel and they want to get to where they are going fast and cheap. If cheap goes away they still will opt for fast.
