Freedom, I know it is not as easy as I suggested.
However, if you move equipment from one hub to another you still need to fill seats. What makes you think there is more business to be had elsewhere, or greater yields than they are already receiving in those markets?
Weather we like it or not, the cost of fuel will be high at least for some time if not for ever. I am currently in Canada on business, and regular gas converts out to more than $4.50 per gallon and it has always been that high here, and currently their dollar is doing much better than ours.
The real problem is, the legacy airlines have sold too many cheap seats to vacation destinations, and now when they need to at least break even on those seats, there is no pricing power. The time to do that is when the economy is good. But what do the airline do, the add more seats to sell even cheaper fares.
So if they reduce service enough, I guess it will mean parking some planes.
