Because of this redesign, I found new ways to earn AA miles!
Under Book Travel, there's a tab for Activities. I can book Danube cruises in Budapest and earn AA miles (beyond just using my AA credit card)? Wow, I never knew that. It was probably hidden somewhere before, but Activities being a tab just like Hotels and Cars made it easy for me to find it only now.
Booking Hotels and Cars on aa.com is uninteresting to me because there are other ways to earn AA miles with those by directly booking those with my favoirte hotel programs and car rental programs. But Activities, I can't earn miles by booking those directly elsewhere that I know of, so to me this
does seem useful (from the miles-earning perspective) even though it may have nothing to do
directly with booking a flight.
