travelling with a bicycle on an airline can be difficult. i’ve never done it before, but i’ve read various articles describing how to do it best. my favorite is one from a former baggage handler. there are a few other tips, but this guy seems like he knows what he’s talking about. the only thing i’ll add to my bag is a document (stating that this is a bike)showing the bicycle fully assembled including a contents list of all parts in the bag. i’m satisfied with my bag, with the lower half cloth covered hardshell and very padded all around.
