I was on a flight from Shanghai to London Gatwick and there was a guy in economy who was dressed in black and wearing a coat. I saw him move up and down the aisles including into Business class and both times he had a small device with some red lights and I could see a camera lens. The second time he had a phone held behind his back with the camera pointing outwards. He sat in the extra leg seats on the front rows of economy class. He is obv employed by the airline but was not dressed like cabin crew, but was standing with cabin crew when we exited the aircraft. Anyone know why China Eastern is recording passengers onboard?
