I have had another of this size AT bags for years and a larger 24-inch bag that is starting to show some wear. I did not want to use the larger bag for this trip because American in its infinite wisdom wants another $25 for baggage checking so we redefined "personal bag" and packed Mary's handbag inside a 20-inch backpack along with the rest of the stuff we wanted to take on our trip. The quality of this bag is great for the price and even when stuffed (not expanded by unzipping the riser) fit easily into the overhead on our AUS-JFK-AUS flight surrounding Christmas. I think the wheels are of slightly better quality than our older unit and the side pockets slightly different. I actually liked this because the upper side pocked was a little larger than envelope-size and held our travel documents perfectly. Inside has the rails from the handle covered by the lining. This actually forms three open compartments the length of the suitcase that can be used to pack some small, flat items that may need a little more protection than T-shirts. When my larger bag finally gives up, I will probably buy the 24-inch size.
