First of all no information was given to us about flight delay neither through sms or call or mail.in fact air india express staff started blaming us saying that all the passengers have been informed on call which was a blatant lie on our face. We checked with other passengers they also did not receive any information about flight delay. They did not show any sign of concern even knowing that we were travelling with 1 child and 2 infants and were coming from chandigarh. If they had informed us in time we would started late or made alternate arrangement. Further, when we asked for hotel accommodation the air india express staff refused on our demand.
After repeated request we were given stay in delhi dare devil lounge which had no food for the infant although we specifically asked the staff to arrange for a lounge with some basic items like curd, fruits or salad. We moved to other lounge on our own expense.
Secondly, we had asked assistance from lounge we were stating in to the flight boarding gate as we had luggage and infants. Although we were given an air india express staff to assist us, however, the staff appeared late at the lounge and made us run with kid and infant to the boarding gate which was quite a distance from the lounge. At least they should have arrange for a go cart.
We therefore request you to look into the matter and assist us in getting compensation for the delayed flight and the inconvenience caused to us. Please find attached our boarding pass for your reference.
