I have used a Trico case and also eBike shipper boxes from Uline. I have never flown without TSA opening my bike carrier. Generally TSA is careful, although they are careful in the way someone who doesn't love the bike is careful. I like using the Uline box as I can fold it up into a small package and then inexpensively ship it to my ride's destination for use to ship my bike home. Unfortunately, a few times they've cut the box open and rendered it unusable for future trips. This trip we're using Airport Ninja bike bags with zippers; I'll let you know how we fare.
