As a woman I don’t like having carry ons when traveling but my favorite type of luggage is my over the shoulder puma bag. Its 11 inches x 7inches x 17 inches. This bag will fit in the overhead, seat in front of you or on your lap. This is why I’m not a fan of hard side spinner luggage. It’s important to have it resting on your shoulder and being hands free, especially when making your connecting flight. If you have to stay overnight at the airport, it’s a nice makeshift pillow. It’s very packable and you will save money on not needing to pay for carry on fees, as it can be called a personal bag.
