I took the Madras Bombay flight on 13th Aug IX602. The schedule departure was 1000hrs. Boarding started at 0945hrs, till the flight took off at 1030hrs there was no AC inside the aircraft, we were continuously reassured by the steward that in the next 5-10minutes we would have AC on. In fact the passengers were sweating. It did not stop here, after we landed at 12noon at Bombay, taxied for about 10min, from 1210hrs to 1230hrs there was no sign of a pickup coach and the AC was shut down. LCC is very well understood by the consumers but not this kind of lack of service. These Government run services should look at Private run LCC to understand how these are run and how they woo customers. Total lack of clarity and complete failure of service levels by Air India Express. Consumers – please boycott AIR INDIA EXPRESS.
