“The tourists wreaked havoc on the three-and-a half-hour flight which was delayed because cabin crew struggled to control the passengers even before take-off.”
With numerous instances (on video) of people being removed from aircraft for seemingly minor disruptions (unruly or crying children), it is amazing that no one was removed from this flight while at the gate. While personal responsibility dictates these drunkards should have controlled themselves, the flight crew should not have departed - or at least had an idea of what they were getting into.
imagine the video of an emergency landing and evacuation with that bunch!
