Richard Heinberg bids adieu to cheap flight:

The airline industry has no future. The same is true for airfreight. No air carrier has a viable plan to make a profit with oil at current prices — much less in years to come as the petroleum available to world markets dwindles rapidly. That’s not to say that jetliners will disappear overnight, but rather that the cheap flights we’ve seen in the past will soon be fading memories. In a few years jet service will be available only to the wealthy, or to the government and military.
