I received this:
22,800 "if you earn at least 57,000 status miles on flights operated by Lufthansa, Adria Airways, Air Dolomiti, Austrian Airlines, Brussels Airlines, Croatia Airlines, LOT Polish Airlines, Luxair or SWISS between 1 March and 30 April, 2010. The additional award miles will be credited one-time, approximately 4 weeks after the end of the promotion."
Those are some weird numbers...
