Shopping for luggage isn't always comparing apples with apples, as there are often lots of optional extra features. Some are built into the bags, while others you can buy separately. Good things to consider include inbuilt USB chargers so that you can power your phone or laptop on the go. You can also get some fantastic tech advancements such as GPS or Bluetooth tracking to keep an eye on your luggage's location. Then there's the option of increased security through a biometric or fingerprint lock. However, if you choose this option, look for a TSA approve one, so they don't have to damage your bag when doing random checks. Finally, you can also look at extra storage such as pockets and pouches to separate your belongings.
