So do I. I never found flying particularly pleasant, whether economy or business class, and after a decade of frequent business flying I pick other alternatives (including staying at home) whenever I can.
But the US travel statistics http://www.bts.gov/publications/national_transportation_stat... seems to say that "people" still fly more - 350 bill. passenger miles in 1990, 530 bill. in 2000, 583 in 2008. Although it's down a bit from the peak years 2006-2007.
