The decision came after the Labour Relations Commission met management and union representatives separately.
It is understood that during those meetings, certain aspects of the Greenfield plan were clarified, though the plan itself remains unchanged.
The Labour Relations Commission has issued a document to the parties which it is expected will lead to the reballot of members.
This evening, Aer Lingus noted the Impact decision to reballot its members on the original Cost Reduction proposals following the union's own bilateral meeting with the commission today.
The company said it now awaits the outcome of this re-ballot.
Within days of the initial ballot, chief executive Christoph Mueller announced he would be terminating the employment of all 1200 cabin crew.
Most would be re-employed immediately, though on lower pay and conditions.
However, 230 would be made compulsorily redundant, with only the bare legal minimum statutory redundancy payment.
Earlier, Aer Lingus Director of Human Resources Michael Grealy said if no deal were reached within 22 days, the controversial redundancy plan for cabin crew would be implemented.
