Air Travel

I just got an e-mail from a traveler who was denied boarding on a WestJet flight. The circumstances were a bit unclear to me, but her fitness to fly was called into question when she had trouble boarding (she stumbled and I think fell) and then spent some time in the lavatory. Somehow they got hold of her medication list, and she believes something on that sent up a red flag. Again, I'm a bit fuzzy on the details, but apparently some of the meds she takes for pain relief are also anti-psychotics. 

Well, it was bound to happen. In the aftermath of the underwear bomber incident,
Canadian airlines are now limiting carry-on items on all US-bound flights. So
what does that mean to disabled travelers?
