I flew to Japan from Florida in May 2002 with two guitars. I bought Harptone 5-ply cases for the trip and both guitars came through without a hitch. The toloex was scratched on one case and that was the only damage.
I padded both guitars heavily and made sure that the peg-head was well supported.
As I said, no problems. I'm coming home in November and I'll pack the same way. If there is any problem , I'll post with the details.
