Air India — Baggage delay

Address:

Mumbai City, Maharashtra, 11374

I and my son flew Air India from Mumbai to Newark on AI 191. On arrival, none of the passengers got yheir luggage. The luggage was not loaded at Mumbai Airport. There is nothing on the website to locate the process of bag delay compensation. The calls and emails to Air India are unanswered. I have had to buy everything while her in newyork in the winters. I am looking for compensation for the delay of our luggage
