@julbpat I do understand the issue of vanity, however, travel is challenging in my case due to the state of my neuropathy. Walking is fairly easy for about 100' and then increasingly intolerable. The Boston-LA trip involved changing planes with a tight window between flights. I knew it would be quite difficult to make the connection on time without assistance. I do believe the connecting flight would have been excruciating if I had walked the airport instead of using the assistance. I'm in my 70's and vanity was comfortably suppressed.
