I have also carried it on and it fit in the overhead bin. I had a letter along from DD's doctor that stated the medical necessity for the machine and all the meds(lot's of liquid!) we were carrying on just in case the TSA's decided we should check it. Also, we brought the manual along so that they could assure themselves that this wasn't an explosive device! Overwhelm them with paperwork and you get anything you want!
