Has anyone took their Bass on the plane?
I travel to Georgia almost every weekend and my brother has a good bass, but it's not my Bass.
I don't want to check it, but will it fit in the overhead?
Carry the bass on as a carry-on luggage. I flew to Missouri earlier this year on one of those tiny Northwest planes and fit my bass in the overhead storage in a regular gig bag. Make sure you don't have any tools in the pockets though, they will make you throw them away. I had my leatherman multitool in my top pocket and TSA flagged it in the X-ray machine. I had to step out of line, unzip my case, let them touch my guitar (I hated that part lol), and pull out my tools. It was either throw it away, or check your bass as luggage in a soft gig bag (I don't think so!).
Anyways, call the airline before you carry on your luggage. As was said before, many airlines will store the bass in the lockers that they flight attendants use.
