I jut crossed over 175000 miles. After I qualify for SE I decided that I would review all other options for international travel, including aircraft type. So far AC has won out, but it looks like my next trip to Asia will be a different carrier. Once an SE, it is not the loyalty plan that keeps me flying with AC. Just too difficult to redeem AE miles for the reward travel I try to book, even with the fact I am now over 2milion miles on AC metal!
