I was traveling with 2 staff, 6 clients. We were extremely early, and in no rush. We followed the directions of the TSA agent who ushered us into a regular line, which surprised me as I would have thought that we would be shown to the line for wheelchairs and families, I hoped for the best until an older client began to lean heavily on me. I got the attention of one of the agents, and long story short, we were told it was just too late and I had asked the wrong questions, anyway. The option he finally offered was just as inconvenient, as it would have broken up the group and disrupted many.
I am aware of the TSA Cares program, but we should not have to "sign up" to receive compassionate care in the airport. (We were also refused a golf cart)
