My husband and I travelled American Airlines in August 07 and I had one big bag, just made the 50 lb limit if I remember correctly! I way over packed for a week in the sun. We ended up doing laundry while on our honeymoon and re-wearing our favorite things anyway. So the best advice is just to pack the essentials & if you have access to a washer and dryer and don't mind doing it at least once, make it easy on yourself. Have fun!
