I had a hard shell case made for my bodhran - a 16" floor tom case cut down. My local music shop ordered it for me. I glued in a half-inch of foam rubber, and the bodhran fits snugly. It cost about $20 American, and it fits in the overhead bin in most aircraft, and if it doesn't, it can be checked safely.The case is an Enduro, made by the Humes and Berg company. I've had it quite a few years now, with no damage to the drum.
