This is a stupid question totally unlikely to elicit useful information. When I was in college, I had a friend from India. He flew home to India on British Airways (stopover in London) for Christmas in the same year that the Pan Am flight exploded over Lockerbie. A few weeks after Lockerbie, he flew to London, was there for a few days visiting friends, then went to Heathrow to fly BA back to the USA. The woman in front of him was wearing a veil and the usual mideastern robe thing. They asked if anyone had packed her bags. This woman, not being the brightest bulb in the pack, said that she had not packed her bags, that was the job of her servants, and she hoped they packed the right things for her trip, but she really didn't know exactly what they packed.
Well, British Airways took her and her bags into a little room so they could see exactly what those servants might have packed...
Actually, that would be a good way to plant something. Pack it in the employer's bag and let them smuggle it, blow up with it, or whatever.
