We had TSA pre check and paid to get it! They told us we would not have to do many of the things such as take your shoes off which I had to do! I’m 78 years old with NO criminal record and. they also patted my ankles down, Why? We boarded the plane in an orderly fashion only to sit there while they perform repairs to the lavatory. Why didn’t they do that before we boarded? I also paid extra to have more room because of my age but that was not what I had hoped for. I know you can’t control who sit in what seat but the guy next to me was bigger than average and took up part of my space.
