I like to use the large disposable box sold by the airlines. It is convenient and requires minimal disassembly of the bike. (Check ahead for availability on your flight). Pedals come off, bars are rotated down and the box is ready to tape up and fly. The assembled bike is protected by it's own wheels, saddle and racks being in place rather than being stuffed into a smaller UPS sized box disassembled. Some non US airlines will provide just a large plastic bag to cover an un-boxed bike with. (Air Canada comes to mind). Indeed, you may have to sign a damage liability release with the airlines to transport a bike this way but, Hey!, a touring bike is to use and enjoy. Not something to worry "what if?"about all the time. I've been flying the bike this way for 40 years with no damage.
