It seems like business availability is at the 9 month mark or so. No more of the 330 days out. At least that has been my experience the last few flights we have had. We fly 3 and once brought my son's friend and even found 4 seats available. Now I do have to say that LX is not as nice as either LH or AS, but still infinitely better than coach. Also, I like the LX arrivals lounge in Zurich for breakfast.
