Thanks to a YouTube video that’s gone viral, millions of people around the world now know that in March 2008, United Airlines baggage handlers broke Dave Carroll’s guitar. Instead of just admitting it and paying for the repairs, the airline kept telling the musician to go away.

He didn’t.  He made a video and the rest, as they say, is music and social media history.  United Airlines changed its tune, promised to do better in the future and, when Carroll refused compensation, donated $3,000 to non-profit music foundation in his name.

Does that mean United and other airlines now won’t break anyone’s guitar? Don’t count on it.  But now everyone is paying more attention to how instruments on airplanes are handled.

Want to make sure your instrument arrives safely? Here’s a video and some tips from the folks at Taylor Guitars and the American Federation of Musicians:
