Austrian Airlines Business Class Smart Upgrade Auction
Austrian Airlines is setting up an auction that will close 72 hours before flight to sell business class upgrades. The winners are based on price bid, but not told other bids. The outcome also doesn't factor in fare paid or miles co-pays, so there is a chance of buying a very discounted fare and flying business class for not much more. Interesting way to maximize revenue, but it's not very sporting since you don't know other bidders' offers.
