Intresting, I was on BHX to DXB and noticed at the gate the ground crew were checking hand luggage for anyone that seemed more. I made a comment that its intresting as the dont to this in LHR, I was told they check everything. Ironically my connecting flight to ISB I was asked to put on the scales, I was only carrying a suit so it was fine yet many did not seem to be asked. Might be who seems an easier target
