Hi,
This is to bring to ur notice that my brother farooq. M. Ahmed travelled on date 16th oct 2017 from saudi riyad to goa via mumbai. Flight detail a1922, a1661 air india. My new purchased american touristor trolley bag is badly damaged n thereis a crack above one of the wheel. Price of the bag is 240 saudi riyal that means 4080/-rs.
When discussing to the person at airpot they say cant help it they r not responsible.
Now who will bear this. Airindia such a reputed dept will behave in such a manner n unneccessary we will have to bear loss because of the irresponsible staff n their character people will travel with other company flights. I want compensation for my loss. Pls do the needfulasap. Waiting for possitive reply.
