I have an SKB case, however I do not know whether or not is this model. They look identical, though. Anyways, last year I was on a total of 14 planes. Due to costs I had to check my euphonium on every flight, and it survived each one of the travels. The case came with two very small keys, so I put a long strand of duct tape on each one in order to make me less likely to use it. Before I left my euph in the hands of the beloved TSA agents, I put duct tape over both of the latches and I stuffed the bell of my euphonium with bubble wrap, but not necessarily in that order. My Wessex was a bit too short for the case, so I used the bubble wrap to prevent it from sliding around. There is clear evidence of the case taking some hits, but it did its job. The case has a rubber handle, so carrying it around for a long time gets to be a bit painful. Hope this helped
