I flew with my little Elna Lotus down to Florida last October as DH was going to a class and I was stuck in the hotel room with no car all week. It's small enough to fit under the seat so I just packed it into a carryon bag, well padded. I had to take it out when going through security, but no issues. I also took a quilt that was already cut out, a cutting mat (18" x 24" fits flat in carryon) and the other necessary items. We shared one checked bag so my sharp stuff (rotary cutter, scissors, ect.) went in there. I got a lot done on it as well as had pool time when the sun was out.
