Yes, to me oversold flights implies the fares were too cheap. The demand was there at a supply over what it should have been. As for Dave''s article, US has already begun rationalizing fares in certain markets. Three day advance (or thereabouts) with no Saturday night stay between DCA and SEA, for example, is about $900 under what it was last year. As a result, I always buy B-class fares now and purposely don''t book too far in advance (mainly for upgrade purposes).
