I booked w/United Airlines and they let me take my machine on the plane w/me to South Carolina, every thing went OK, BUT on the way back to NM they changed their minds an made me put it under the plane in the luggage department. I saw the luggage people THROW my bag w/my machine on the luggage rack and then pile more luggage on top of it!! My machine was damaged, I filed for a claim, their response was that I did not pack it correctly! Good Luck with your machine. I will not fly with United or take my machine on a plane again.
