I have booked business class for my father flying from dammam to lahore. I dropped him at the airport and got boarding pass with seat 1F on flight XY 883, 30 JUL 2019. After he went pass the immigration he was moved to economy class. I am really distressed I booked and paid for the business class ticket for my father because of health reasons, he is 72 years old and he was made to change his seat to economy class. totally unacceptable. My father suffered psychologically, emotionally and physically. There is no justification for this really really disappointed.
