Here is a post back in 2011 on "Crazy Quilt Mom's" blog (Fabulous Blog) in August of 2011...be sure to read all the comments too. A lot has changed since then I would call the airline your flying and ask them for sure and you won't be surprised when you get there. Happy flying with your sewing machine! http://crazymomquilts.blogspot.com/2...g-machine.html
