hi,
why does everybody think that such generous milage-offers will stop to exist with miles&more ??? m&m is just the new frequent flyer programme of swiss - sure, lufthansa does not make such offers for its own fleet but lx will stay a "more or less" independent airline with its own (swiss) management. to fill their planes they will still be able to do such promotions - they are just using another technical platform for crediting the bonus miles. os for examle does some "own" milage promotions if you fly os metal (e.g. see
here...)
so relax and see what will come next year ..
