I just got the e-mail below for American Airlines Cruises. I was curious if anyone on here who takes cruises has ever booked it through American Airlines before and what your thoughts are. Or, if when booking on a boat, referred it to AA as your Travel Agent to get bonus miles. Any negatives of booking with AA?
