We have never experienced an open search on anything. The TSA has X-rays and computers that is expected to do much of the work for them. The TSA has tape and other tools to reseal items if they must. We also throw our own short roll of tape in as we close the lid. Like much in life many things come down to how you behave, appear, present, and carry yourself. Please note millions of pounds of seafood and beef are flying on our passenger planes each and everyday. Our igloos have traveled the globe since 1979 without issues right next to our dive gear.
