As I said in the other thread ... I travel all over with my Gibson B25. If you're familiar with its size ... it's larger than a baby anything but certainly smaller that an jumbo or dreadnought. I don't use a hard case ... just the old fashion kind that came with it. Rick Fielding told me to walk onboard the plane with it as if nothing was up and if they did say something, to beg the flight attendants to let you take it onboard. I, so far, haven't had any trouble. It fits in the overhead with a lot of room to spare and I encourage other people to put their carryons around it. I've never had a problem with someone trying to abuse it while loading their stuff in the bin. Maybe it's because I'm a short little woman and they kind of miss it. Of course, it they really gave me a hard time I would point out the size of the carryons that they did let on ... most of which are much larger and bulkier than my guitar case. I arrive, guitar in hand, with a big smile and a host of optimism written on my face ... moonchild
