Yes, you can wear your Apple Watch to the airport and through most of the travel process. At the security checkpoint, TSA and international security agencies generally allow you to keep your watch on while walking through a Millimeter Wave Scanner (the large, circular machines where you raise your hands). However, if you are directed through a standard Metal Detector, the metal components in the watch or its band may trigger an alarm, and you will be asked to remove it. In 2026, many airports are transitioning to advanced screening tech that minimizes "pat-downs" for small accessories, but it is always best to be prepared to place it in your carry-on bag or a bin if requested. For the most "seamless" experience, many frequent flyers place their watch inside their jacket pocket or carry-on just before reaching the front of the line to avoid any delay. Once past security, your Apple Watch is a vital travel tool for 2026, holding your digital boarding passes and providing real-time gate change alerts.
