If you go to Wallmart and buy a camping bed roll the sort that is made of a hardish foam about half an inch thick and about 18 inches by 6foot long and costs about $5, and cut two pieces the size of the inside of your case put one below and one on top of the guitar This will help insulate and also gives an extra layer of anti dent material between your instrument and the luggage handler. I have used this on a number of occasions and my instruments have so far come out without damage Cheers Bill
