People seem to think that using a wheelchair has benefits. I'd gladly trade places with anyone who wants to use my chair. I'd love to be able to stand in line again.
I've posted before, but a few years ago, there were 30+ people in wheelchairs waiting for one flight I was on. I was the only one who couldn't get up and walk when it was time to board. I was pre-boarded because of the need for assistance. The others were pre-boarded too, but every one of them walked to their seat. Seeing that bothered me, but I'm sure some of them were for real.
