Aer Lingus is cutting up to 900 jobs.
The airline met with trade unions this morning and informed them it needs to reduce its headcount by up to 20%.
It says the cuts are necessary due to the collapse in demand for air travel.
Aer Lingus employs 4,500 thousand people, meaning up to 900 jobs are at risk.
The airline is putting together a proposal for a voluntary redundancy scheme, which will then be put to unions.
In a brief statement, Aer Lingus says it's continuing to communicate directly with its employees and engage with their representative bodies.
It comes just hours after Ryanair announced the loss of 3,000 jobs.
