The New York Times reports that while even complimentary mini bags of pretzels inch closer to extinction, airlines are dreaming up new elite categories for frequent fliers -- complete with perks and prestigious titles.

A quick sampling of the new clubs: Continental Airlines' Presidential Platinum (customers must fly 125,000 miles or spend $30,000 annually); Delta's Diamond Level (also 125,000 miles per year); Southwest Airlines' A-List (16 round trips in 12 months).
