This morning on NPR an airline industry expert was talking about how airline fares don't accurately reflect how much it costs us to fly. Realistically, we should be paying 25% more for each ticket (a $400 ticket really costs $500). Instead, we potential passengers pressure airlines to keep their fares down, because of every online search for "lowest fare." Each airline must keep their fares at least $1 lower than their competition, hence the $25 bag check fee, and fees for aisle, window, or "premium" seats, etc. So who IS paying for the cut rate fares?
I find it interesting that the Carol Burnett show had the answer to this dilemma; what, 30 years ago? http://www.youtube.com/watch?v=QCz8he36hsk
