My mother has travelled through airindia from minneapolis to hyderabad on june 26th.
Minneapolis - chicago delhi - hyderbad
Passenger name - sujata kallepalli
Itinerary is flight/date: dl 2424 / 26 jun / ai126 / 27 jun and ticket number:[protected]c1.

We had 2 check-in luggages which were delayed to deliver by 3 days

1st baggage has missing fossil watch which is $100.
2nd baggage delivered on 1st july at 11.00pm with no items in the bag almost empty.

We have lost 10kgs of items worth of 400 us dollars including 1 fossil watch, clothes (6 nike tshirts, 2 puma tshirts, 2 gap kids tshirts, 3 adults gap tshirts), 2 packs of linda chocolates and bath & body works (8 mists, 1 body wash, 2 body creams)

I have spent $1500 ticket and lost almost $400 worth of items.

The air india airlines is responsible for our loss and mental pressure.

Hope they take this seriously and handover our missing items or refund us $400.
