Wheels are not always best for carry-on luggage

It may be hard to remember, but not so many years ago it was rare to find a wheeled suitcase. For a shorter trip, a simple duffle or small backpack might suffice and will lighten your load considerably since the wheels and handle add at least 2 or 3 pounds to your bag. The lack of wheels also works in your favor if you are flying on a small commuter plane, where wheeled bags must almost always be gate-checked. And if you are going onto a train or subway after leaving the plane, it’s sometimes easier to walk with a backpack or duffle over your shoulder.
