Air India Express — ix 373 - flight delay

My wife is a regular passenger in this flight from TRV to CCJ (to and fro) on a weekly basis

On 08/07/2019, it is delayed by two hours but there is no prior intimation. Some times she has to wait in the airport, without having any intimation from the authorities. This is not an odd incident. This happens at least once or twice in a month

It is quite annoying that an airline of Air India flag has such an irresponsible and annoying behaviour in the operations. The operations department should consider the inconvenience and loss happened to the passengers, because of this behaviour

PLEASE DO SOMETHING FROM THE MANAGEMENT SIDE TO MAKE SURE A RESPONSIBLE OPERATION OF FLIGHT
