The business that owns and manages Cork and Dublin airports lost €284m in 2020.
That's among the details its incoming chairperson will tell an Oireachtas committee later.
Basil Geoghan will tell politicians the financial future of the group is under threat if airport charges aren't reviewed.
Eoghan Corry, editor of Air and Travel Magazine, says €284m will be tricky to recoup because air travel is totally different now.
"It's a colossal amount of money for an airport, it's a colossal amount of money for an airline.
"It's particularly difficult when all your other revue streams that you would have expected to kick in in 2021/22 have been compromised.
"The airport experience has changed right across Europe."
