Aer Lingus management has resolved disagreements with around 2,000 SIPTU workers at the company.
The disagreements had centred on the payment of increases due under the PPF agreement, which had been frozen during the implementation of the company's survival plan.
Following negotiations, SIPTU staff have agreed to working practice changes that will facilitate the speedier turn around of aircraft and 18 other measures.
In return Aer Lingus has agreed to pay the second PPF 4% increase and restore overtime payments to double time, backdated to 1 March 2003.
The Labour Court ruled in April that unions must negotiate further working practice concessions in return for the PPF payment.
SIPTU branch secretary Christy McQuillan said members will be balloted on the new arrangements in early June.
A spokesman for Aer Lingus said the company welcomed the fact that unions were accepting that constant change was vital to succeed in the aviation industry.
Aer Lingus has also agreed to pay workers the 3% pay increase due under the new Sustaining Progress agreement from 1 July.
Separate negotiations with cabin crew – who are represented by IMPACT - have yet to reach agreement on whether staff will sell food and drink on board for commission, in return for the 4% PPF payment.
