JNB has a big issue with their employees...
I worked at JNB for 30 years and the baggage pilferage problem, which reached epidemic proportions a year or so ago, is still prevalent. Outgoing bags as well as incoming are at risk.
If this is the case where are the airline security people to watch over the crew baggage? As baggage is being tampered with where does this happen? in the hold? in transit to the customs area/crew baggage drop off point? or in the terminal?
If this is an ongoing problem as some have said, then airlines need to tighten their security up instead of wondering what liquids and gels are in the hand luggage.
In my airline we have a problem with crew baggage being broken into. The crew security seals do not appear to be a deterant.
If that was me I wouldn't have touched it and ask for Customs to inspect my case in front of other officials.
