Question for the FT crowd - When I was in line at the AC desks in T1 international I noticed a group in front me of with many large boxes as their luggage and all were inside plastic wrap of many layers. Then I noticed what appeared to be a concession at the end of the counter that has a sign for "luggage wrapping". People were putting their luggage into these mummy-wraps, just like the boxes, presumably for a fee. The luggage that came off my flight in MAN had no wrapped luggage - so where did it go? I asked in the line and some said that it avoids theft in places in Asia but no one was sure. Does someone know the real answer (I doubt that preventing the salami smell from spreading is the reason). Also, I was told that I shouldn't lock my checked luggage because it may be opened. If that is the case, doesn't the wrapping create a security issue? Does this delay luggage processing? Why is it encouraged?
