I believe Rick is right about having to check a bow. At least that's the way it was the last time I flew with one. Ironically, I've had more problems using the hard cases with cut out foam slots than ones without the slots, even though theoretically they should offer more protection. This is because the TSA opens the case and takes the pieces out of the slots and doesn't try very hard to get them back in the slots, so they end up jammed against whatever else is in the case, like arrows, bow square, whatever. My best luck has been the tubular cases with sleeves for the limbs. But I don't put anything in the bow case that might scratch the bow, even if I pack it so it won't scratch it. Frankly, I would worry about traveling with a one piece bow, unless I had a sturdy one piece tube to put it in. Since the dimensions would be irregular, you might want to check in advance to see what the charges would be.
