I travel by plane for business. If you don't have a TSA pre-vehicle inspection, you may be forced to remove the belt. If you have a TSA precheck, you should be able to keep your belt on. In any case, a non-metallic wrist strap is great as it will not set off the 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.
