As a person *with* a service cat - a Trained Bengal (who is hypoallergenic, as he has hair, not fur, and doesn't produce dander), I still make sure that I keep him in his carrier (as uncomfortable for him as it is, since he's huge) when we're on an airplane, because people just freak about cats in general. Most people see *him* and their first reaction is to just be like "Wow! He's gorgeous! I want to touch him!" And while he's friendly and all that, it's not cool to touch a working service animal.
I always ask the people around me if they're allergic though, and then if they say they are, I'll ask to be reseated so as not to bother them.
I usually travel in first class though, to give him the extra space he needs to stretch out if he wants.

for the ultimate showdown between the highly allergic to cats guy vs. the woman with service cat on the same plane. 

I totally agree. And allergies often have a psychological component. I had a friend who swore up and down he was allergic to animals- all animals with fur.
We went over another friends house and turns out the cat had been sitting under the futon the whole time. Nary a sneeze, sniffle or cough from the one with the supposed allergy.
They just put them in the basement when he starts getting symptoms. I myself have issues with cigarrette smoke- thank God people can't smoke on planes anymore.
Morphine is supposed to make you sleepy. Or the drug seekers who are allergic to everything that is non- narcotic, lol.
