I have very unexpected experience about staffs at Delhi airport...In fact they went out of their way to help me locate my misplaced luggage...They searched for it along with female officer as an escourt (which was highly unusual) found it in the end with everything intact. I was the among the last passengers to board the aircraft due to the the whole affair of misplaced luggage. Advice: Dont act arrogantly or get angry for some minute inconviniences. If you do, you are looking for trouble that you would not have gotten in the first place.
