There are fears for up to 350 Aer Lingus jobs at Cork and Shannon airports.
It comes as the airline considers closing its bases at the two airports.
Aer Lingus had previously said it's planning to lay off around 500 workers due to the impact of Covid 19.
Today it was announced that the company has lost €316 million so far this year due to the pandemic.
Willie Walsh, chief executive of parent company IAG, says it'll be years before air travel returns to normal levels:
"We were hoping to get back to 50% of our capacity in July, we're flying at about 20% today, so this is a much slower buildup in recovery than we had originally expected.
I think the industry consensus would be that it'll be 2023 or 2024 before we get back to 2019 levels of passenger demand"
