This is my first post in the HP thread, but as a frequenter of the US forum I feel as if I know some of you by now.
My corporate travel department booked me in paid C LAX-LHR-HAM on BA for September. I know that you cannot accrue AA miles on transatlantic flights. Can you earn HP miles on transatlantic flights? What about the LHR-HAM-LHR legs?
I'm sorry if these questions have been posted ad nauseum, but I did a search, and I couldn't find a clear answer.
