Two investigations in Ireland and the US were carried out into an incident on an Aer Lingus flight where two flight attendants were accused of being drunk, abusive and threatening to passengers.

Passengers had been expecting a relaxed, uneventful transatlantic flight, but what they got was several hours ‘terrified at the hands of an intoxicated and out-of-control flight crew’, reports Conall Ó Fátharta.
