One bit of advice:

LOCK THE CASE!!!

Flying to Chicago from the Winnipeg Folk Festival (1979?) I picked up my guitar & banjo after the flight home and took a cab home. On opening the guitar, I found a hole in the top ala Willy Nelson. Strings still in tune. No sign of anything on the case itself. I hadn't insured it.

Going to Winnipeg I had watched the guitar in it's case fall off of the conveyer while being loaded into the plane---quite a fell---20 feet or so. It was fine after that. But I did sweat some during the flight.

Yes, it's a good idea to lock your case. Maybe even tape it all around with duct tape. I strongly believe some folks opened my guitar and were pickin' on it (and doing whatever to it), when it got that hole in it!!! Insure it too.
