I bought this for my husband for all of his suits, because he travels every week. Based on other reviews, I thought it would be good as a carry on. When I read the dimensions it seemed like it would work. It will work as a carry on for some planes, but not most, unfortunately. The shape of the bag is square, not rectangular; you will most likely have to check this bag. I decided to keep the bag, because it is a good bag to check. Instead of using a suitcase, which will leave your clothes wrinkled, this will be a better option. Just check the airline ahead of time to see if you have to check or carry on this bag. Still a great bag. Good quality for the money.
