I know I've seen this mentioned before but I couldn't find the thread using the search. I'm going to NAMM in two weeks and there's a good possibility I'll be picking up either a bass, guitar, or oud on the last day of the show. What do I need in order to fly back home with the bass? Do I need a flight case or will a solid hardshell case work okay? Do I need to try to get ahold of 'Fragile' stickers or is that useless?
