Roben, I just used a regular, I think it's a 19", suitcase that is the carryon size. I turned the machine on the side so it was sitting on the bottom of the suitcase but I had no problems with the operation of it once I got to CA. Good thing DH is traveling with you. I had to look all helpless and needy. I must say it worked well, hehe. Although, there would have been no way I could have lifted it myself. Have a wonderful trip and contratulations.
