Even though I have two Featherweights, my go-to travel machine is an Elna Lotus. Mine is a 1976 SP model. It has ZZ and utility stitches, although I would not use it for heavy sewing. It had fold-up sides and is lightweight (although not as lightweight as a newer plastic machine). I got mine at a garage sale for $5 but do usually see them listed for more.
I took mine to Florida last year in my carry-on bag as I was going to be in a hotel room with no car while my husband was in class all week. I also took a pre-cut quilt project, and a cutting mat. The rotary cutter, scissors, and other sharp items were packed in our checked bag. It worked out great.
Another good choice would be one of the small Kenmores (158.10xx). I have had a couple of them (a 1040 and a 1050) and they are sweet little machines.
