Recently I was seated beside a passenger who needed more space to sit and was almost taking away some on my space which made a 4 hour flight very uncomfortable. As flight was full I couldn't change my seat. Do I have any option under such situations like compensation from airline ? Are there any restrictions on max space which can be taken by passenger in a flight.
Just to add my question is more from my rights perspective. I understand the situation for other person, it's very difficult for him.
Edit:
Just wanted to add that I was flying by GoIndigo airlines, it's a low cost airlines.
