Define your need. You will need a smaller, lighter cart if you are just carrying one bag to the airport; you will need a heavy duty cart if you are carrying several bags at a time.
Choose thick wheels with treads if you are pulling your luggage a distance, down a street or through snow. Thicker wheels drive better and stop the cart from tipping over.
Check the length of the handle. Tall people will prefer a longer handle that allows them to pull the cart without bending over or stooping.
Measure the width of the carrying platform. Then determine how many pieces of luggage fit standing up or lying down.
Determine the weight. Sturdy wheels and a longer handle can add pounds to the luggage cart. You may want a small, light cart if you have to carry it onto an airplane and store it overhead.
Pick a luggage cart that folds up for easy storage. Whether you will store it on an airplane or in the trunk of your car, you want a cart that takes up the least amount of space.
Determine the weight capability of the luggage cart. Know what you will be carrying and make sure your luggage cart can safely carry the load.
