This is a tricky one... I have no experience but some digging found this on the miles and more website (which covers the LY codeshare range):
*On selected LX code share flights within the ranges LX4220-LX4239, LX4270-LX4279, LX4600-LX4639 und LX8000-LX8499 you are earning award miles only. Status miles, HON Circle miles and Executive Bonus are not being granted on these flights.
Whether they carry this policy over to *A or not I can't say... UA isn't really going to be able to help you here, if you want a firm answer talk to LX.
