Anyone had the experience of disclosing mental health disability to a flight company? I’m flying Europe next month and because I wanted to sit next to the window to get less nervous, I asked the flight company if they can assign me the seat. 

It seems they want to escort me to the flight now. I’m wondering if they will deny you to get on board due to mental health problem? ( I am functioning pretty well) but not sure if they will just deny me anyway.
