I use a carry-on suitcase for my Janome Jem. . I kept the styrofoam packaging that the machine was packed in. I ended up using only the front piece (the piece that the face of the machine fits into) I cut channels for the pull up suitcase handle, so that it nestles in and can be secured with the suitcase's inner straps. My Jem has traveled on an airplane several times and I love that it conforms with airline carry-on regulations.
