Rich, I would suggest contacting AAdvantage Customer Service directly to make certain which fare codes are acceptable. I recently flew BCN-FCO on IB. It took AA probably fifteen minutes to find our if the fare class was acceptable. The reps. screen had something similar to "effective May 1998". I am not certain why she was so amazed that I asked her to please get an update from someone considering that is is the end of 1999! Several other threads have posted applicable fare classes, but if only $95 stands in the way of 100K, I would call. Good Luck!
