I need to book FRA-ATH and am looking at a RT on Agean. Outbound is fare class P, earns zero miles, return is K which should earn 100%.

Question: will I get the miles for the return, or will the fact that it's a round trip mean the outbound P fare will cause me to get zero miles for the entire trip?

(This is my last trip for 2010, and I'm 200 miles short of 1K, and Agean is cheaper than LH)
