It's quite convenient, but only if we both have them. When she had one and I didn't we got no assistance whatsoever. I had to pass through security with all my carry ons, shoes etc PLUS hers and then I had to put it all away, get her shoes on, mine too. I backed up that security line like nobody's business. With us both on scooters, they separate us and aTSA agent helps each one of us. They take us off to the side, and we don't hold anyone up.
