Look at the size that you want. You'll want to make sure that you get one that's airline approved, since they restrict the sizes, when you try to bring them on board. Make sure that you get something that's good for you.
What do you want in terms of features? Do you want 10 different pockets, or do you want one big console that you can throw all of your clothes into? This matters a lot, because you will find that they all vary in sizes.
Do you want wheels, or no wheels? When you get luggage with wheels, it's going to weigh down the luggage a little bit. You'll want to make sure that you get something that's not too heavy.
When you spot one that looks good, you'll want to look into the pricing, as well as the reviews online. Make sure you get something that's made of great quality.
