4.) You Are More in Control of Your Luggage
We have all heard of some cases of airport drug smuggling trials where the accused maintained that the illicit products were planted in their baggage without their knowledge. Since then, security concerns have been rising significantly, and for a good reason.
You don’t want anyone tampering with your luggage, especially in a crowded airport.
You should keep your luggage with you at all times. However, between the rush of looking for your terminal and asking people for directions in an unfamiliar airport, things can get messy. You are at a higher risk of taking your eyes off your luggage, even for a few seconds.
For an extra security measure, and to make sure no one has access to your luggage other than you and the TSA agents, always have your bags zipped and locked.
