I'm traveling by plane on business. If you don't have a TSA pre-vehicle inspection, you may be forced to remove the belt. -Check if they should allow you to wear a belt. In any case, a non-metal bracelet is great as it will not set off a magnetometer (metal detector). I appreciate that I can avoid additional validation (rambling and explaining). The Betta Buckle requires only a simple "latch" to secure (or unlock) it. 1 1/4" wide fits most "nicer" (khaki) pants.
