This has been going on for some time.
A couple of years ago I was on a SAA flight to Atlanta. On the flight to Seattle I discovered that most of my cash dollars had dissapeared from my wallet. I had no idea how or where this could have happened.
I met up with a SAA B767 crew in Seattle during their Sim training and told them about my loss.
They told me then about this huge problem that SAA have. Whether this is the first one they caught or if there were others I don't know.
It makes me sick!!
