Thanks for the thoughtful replies. For myself, I wouldn't call it an accomodation, as there's no reason I can't wait in line like anyone else.

So it's more of an entitlement. I can't see that my taking it would hurt anyone else, or deprive them of a chance to cut a few minutes off their wait, so why not do it?

Sylvia's right - if I had requested an airport wheelchair and had a pusher, I probably would be taken to the elite line. I can't be pushed (low back, no handles) and don't want to be, but maybe I should take that as the standard.

Edited to add: I've found the disability forum on Flyertalk to be pretty inactive, unfortunately, and dominated by concerns about how elderly relatives, etc will manage infrequent travel. There don't seem to be very many regular travellers with disabilities who care to post there.
