Looong story, but thats just how LH operates: rather fly empty than give a away premium seats (creating the impression that you don't need to pay big $$$ to get into the premium cabin). LH feels confirmed that their logic works as they mint money in the premium cabins on longhaul even with an inferior product (compared to their benchmark AF/KL & BA).
