I've been planning an AONE4 to take advantage of the AA 2015 bonus promo, which can yield tons of miles. (I'll earn over 200K redeemable AAdvantage miles.) I just broke a bone in my foot and will be on crutches for approximately two months. I'll be using a wheelchair in airports. I think that the only time it could be a real problem is when I arrive and leave on the same aircraft.

Anyone here have any relevant experience?
