I use a top-of -the-line Calton bulletproof fibreglass case (made in Canada from Elderly Instruments) when I fly with my guitar. Yes, I check it. I added another 2 d-rings so that I can attach 2 shoulder straps and carry it on my back. When I'm doing gigs that I drive to - mostly on the East coast- I use a very fine Levi padded guitar-bag (also made in Canada) with padded shoulder straps for toting on my back. Never had a problem with either. Strongly endorse both. All the best. Seamus
