If you don't want to bother with the hassle of checking in your luggage, being charged baggage fees, and potentially losing your bags, consider an adaptable carry-on. If you're wondering what that is, it's a flexible luggage that has bags attached to it so it'll still be counted as one piece since they are all stuck together. These adaptable bags are measured to easily fit into the cabin storage space. If you're keen on getting one, check out the Balanzza Truco ($199). Remember, you can always make the most of your carry-on by using vacuum bags!
