Hi, I used to do this with the Rollz I had for my late husband. There’s less chance of them damaging what is an expensive piece of equipment. The can use the transfer chair to access airplane seat. Ensure you book assistance at the airport via your airline! They can use their wheelchair and you could walk with the Rollz type convertible folded. I had a bag for it and wheeled alongside. Anything to avoid it been damaged by putting in the hold. Hope this helps
