I shipped/brought my guitar on the plane with me from Boston to Montana one summer. I would not advise doing it again. The difference in air pressure, altitude, handling, my imagination...kinda' messed it up. I brought to a shop to have it fixed/re-set-up for a whopping $12 and then it was better. And that was in a semi-hard case - the thick cardboard style (in between soft and a full hard case).

Best of luck.
