Welcome from me also. At this point there would be many more contenders for worst program than best. You could also have sub-categories for:

** Steepest decline
** Most difficult redemption
** Most meaningless elite tiers

I doubt your airline clients would like it very much but you'd get more press this way. Skytrax, Conde Nast Traveler and the former Freddies are already so prominent in this arena, it's hard to see what value another similar award program brings. A negative one, however, makes you the Razzies vs. the Oscars: guaranteed press.
