Air India Express — Flight delayed by almost 4 hours Del to Koc

Delhi to Kochi flight on Dec 3rd scheduled at 4:00 pm is delayed multiple times. First they notify that the flight is delayed by 30 mins at 4.30, then rescheduled to 7.00 pm and then to 7.50 pm and then 8.30 pm. None of the crew members present at the gate. My parents aged 67 and 58 had to go through the turmoil of waiting and getting delayed. They would reach kochi only after midnight. Absolutely no concern shown by the airport staff, they could have shown some attention to the passengers by providing food or atleast water. Pathetic service
