The employers' body IBEC and the Irish Congress of Trade Unions have intervened to try to resolve the Aer Lingus cabin crew dispute over rosters.

The two organisations have invited the national secretary of the cabin crew union IMPACT and the chief human resources officer of Aer Lingus to brief them on the dispute to see if any assistance can be offered towards finding a resolution. Both sides have accepted the invitation.

The meeting will take place tomorrow, though a time and venue have not yet been fixed. IBEC will be represented by its director of industrial relations Brendan McGinty, while ICTU will be represented by general secretary David Begg.

Earlier this week, Aer Lingus told the stock exchange the cost of hiring in planes and crews from other airlines during the dispute was 'not material' at the moment. But it added that a continuation of the dispute could hit passenger bookings which could, in turn, have 'a potentially significant impact' on the airline's financial performance.

The cabin crew union IMPACT had claimed the cost of hiring in planes and crews could top €400,000 a day - and could be even more if they were hired to operate transatlantic flights.
