Take a picture of you next to your luggage
This might not have crossed your mind, but police recommend taking a picture of you next to your suitcase; try for the check ticket number is visible. That way, you will be able to prove the suitcase is yours in any awkward situation.
Choose a durable model without zippers and with a code
It’s very easy to open a suitcase that is only protected with a lock. Next time you go to buy luggage, look for a model that doesn’t have zippers and comes password-protected. Luggage made of a stronger and harder cutting material is another option. Remember that although it may initially seem expensive, it will last longer, so you may enjoy it during several trips.
Place some kind of detail to identify your suitcases easily
Identification tags on the suitcases are no longer enough to secure them. Hang some bright color ribbon or a sticker that makes it easier to recognize. This will not only save you time when picking up your luggage at your destination, but will make it easier to find if lost or if there’s some confusion.
Have a list of everything packed
Save in your hand luggage a list of the things you’ve gotten into the hold-traveling suitcase and if possible, take a picture of what is inside before you close it. In case of theft, you’ll quickly realize of an object that does not belong to you. Do not spare time on these tasks, they can be very helpful.
