It seems like everyone's having issues on planes these days. When this passenger with special needs is conflicted, they take to to the popular Reddit forum to ask:
I recently had to travel out of state to visit my family. I have a psychiatric service animal for my bipolar/schizoaffective disorder and Lula my chiwinnie accompanies me. I always have to sit in a window seat so I can see what's happening(I fear planes).
Apparently, the person next to me has a terrible dog allergy. They asked the attendant that I be moved and I said I would move to another window seat. They found another seat but it was an aisle seat so I said I couldn't do it.
The man beside me refused to move to the other seat because it wasn't economy plus with extra legroom like we were sitting in. The guy was very rude the rest of the flight to me and the attendants.
