Yes, I can only echo the thoughts of others on this thread. Go for it. Even if you fly for business, in business, it's worth it for the bonus. As others have said, if you do fly some economy (personal or otherwise), it makes the ground part of the travel a lot more convenient (priority everything + fast track check security + you're higher up the pecking order when things go wrong).
