We received our AA reservation changes yesterday (DTW to SXM), in an email. The original reservations were made in August. The times of our flights have changed, leaving us with a 4 hour layover in Charlotte on the way home, and arriving at 12:30 am the next morning -- as well as unpleasant changes to our so carefully chosen seats on several of our 4 flights. This seems to happen every year and we are so upset with AA. But Delta flights from DTW are ridiculously priced, and the connections are horrible.
