My parents aged 65 and 78 yesterday travelled from Houston to Karachi via Doha. They complained that food was not good and airline staff was not responding to their calls. In one incident my mother wanted water from long time she tried calling staff but nobody came as she had front economy seat and she cannot walk long as she is old and had wheelchair assistance. she walked passed business class to the service area and asked for water. The staff replied this is business class service area go back to the end of economy service area to get water. my mother told her that she is dying from thirst and you are not responding, then she gave her water in a glass she had drank 2 glass there (She did not even give her a bottle to take). I am very upset with this type of behavior.
