Keeping your luggage safe during a stopover requires a multi-layered approach to security and "situational awareness." First, if your bags are not checked through to your final destination, you should utilize official airport luggage lockers or "Left Luggage" counters, which are monitored by CCTV and often require a security scan of the bag before storage. If you are keeping your bags with you, never leave them unattended, even for a few seconds; use a TSA-approved lock to deter opportunistic theft and consider a "luggage strap" to prevent accidental opening. In 2026, the gold standard for peace of mind is using a GPS tracker like an Apple AirTag or Tile inside your suitcase, which allows you to monitor its location in real-time via your smartphone. For added physical security, some travelers use "luggage wrapping" services that encase the bag in layers of plastic film, making it tamper-evident. If you are sleeping during your layover, loop a strap of your bag around your arm or leg, or use a "laptop cable lock" to secure your carry-on to a fixed seat, ensuring that no one can walk off with your belongings while you are resting.
