Two weeks ago--ATL-LAS 12 wheel chairs. Upon landing I saw 4 of those who supposedly needed them in ATL moving without issues in LAS. Could have been more, but I was upfront on a 757. So those are just the ones I saw. And yes, the wheel chairs were waiting in the jetway. They just hustled past them trying to beat everyone to the escalators to the trams. I fly this route (and vv) frequently. This behavior happens on almost every flight.
