These look great! John and I are constantly travelling with a guitar. We live in California, but John works in Washington DC, so he's on a flight across the country every couple of weeks, often times with a guitar in hand. Our current case is starting to get pretty banged up. Sometimes we're able to sneak it into the coat section in first class (before proceeding on down to coach, of course!), but usually, a flight attendant has to check it at the plane. Who knows what they do with it from there... It's probably good that we don't know, actually! But a case like yours would help us rest a little easier. We'll definitely keep it in mind in the future, when we're ready to replace ours. Is it possible to make a relatively light hard case? Weight is my big issue with our current case. I carried it for awhile a few weeks ago, and my hands are still peeling.
