 In 1984, the airline formed a fully owned subsidiary, Aer Lingus Commuter, so that Aer Lingus could fly to larger cities in Ireland and Britain whose flying time from Dublin did not require jet aircraft.These services employed five of the Belfast-built Short 360 after conducting a trial with the Short 330.Around this time Aer Lingus purchased a majority shareholding in the cargo airline Aer Turas, owner of some DC-8 freighter jets.
