The Transport Minister has said a decision will be made shortly on future funding for regional airports.
It is understood the subsidies provided to Sligo, Galway and Waterford airports are under threat.
Minister Leo Varadkar said regional airports had cost the Government €200m over the past 10 years and that it simply could not go on.
"I think it was justified in the past when the road network wasn't as good and we needed to access remote regions and connect people to the main airports…I don't think that's justified in the future," he said. "And even if I did think it was justified, we don’t have the money anyway."
