Did u baggage is exchanged with some body who is having similar type of baggage like yours? Read my experience
Some time back I was traveling from London to Bangalore by British airlines, I checked in my luggage and got boarding pass and luggage tags, I reached Bangalore airport and waiting for my luggage I pickup the baggage which look like my baggage took it and went home, my family members are very happy, since it is late night I did not open the baggage, next day morning I asked my wife to clean up the cloths which are in the suitcase, since I did not have key I misplaced some where, I asked my wife to break the suitcase and clean my cloths, when my wife break open the suitcase my wife saw the women cloths and soiled pants of women, she started screaming and asked me to come into the room where the suit case is kept. To my shock I asked her how come the women cloth in my suitcase? When I carefully saw the suit case I checked up that this is not my suitcase, I virtually shocked, and I do not know what to do. Immediately my phone rang, when I lifted my phone I heard a women voice asking about me, I told that I the person u wanted is speaking, she said that she is profusely sorry because my suitcase was taken by her and she asked me my detailed address, I gave her, next day morning she brought my suit case and I gave back her suitcase. We become good friends, any thing like this happened to u? if u wont trace the person who has taken u bag what u do?
