Dublin and Cork Airports have made a combined loss of €150 million since the Covid-19 pandemic began.
The DAA, which operates the airports, will tell the Dáil's transport committee today the aviation sector has been 'demonised' recently.
Cork Airport was expected to host over 2.6 million passengers this year, however Covid travel restrictions have seen that figure drop by 95%.
Ryanair are now threatening to close its base here in Cork for the winter, if the Government does not adopt the EU traffic light system for international travel.
Sinn Féin's transport spokesperson, Darren O'Rourke, says the government needs to take immediate action.
