Whether you can wear metal bracelets through airport security depends on the density and volume of the metal, but generally, small or thin bracelets are permitted, while large, "chunky" jewelry will likely trigger an alarm. Most modern walk-through metal detectors (WTMD) are calibrated to ignore small amounts of metal like a wedding ring or a thin silver chain. However, if you are wearing a heavy "cuff" bracelet or multiple bangles, it is highly recommended to remove them and place them in your carry-on bag (not the loose bin) before passing through. The most notable exception is the Cartier Love Bracelet, which requires a screwdriver to remove; TSA agents are very familiar with these and will usually perform a manual "pat-down" or a specialized wand sweep rather than asking you to take it off. In 2026, many airports use Millimeter Wave scanners (the "body scanners") which detect objects based on shape rather than metal content, so any prominent jewelry will show up as a "highlight" on the agent's screen, leading to a physical inspection regardless.
