The leader of the Seanad, Mrs Mary O'Rourke, has called on political parties to re-declare donations received from Ryanair boss, Mr Michael O'Leary.
She said the public must be reminded of such donations while legislation for the break up of Aer Rianta is processed.
Mrs O'Rourke told the Seanad that she accepted that a donation of €63,487 made by Mr O'Leary to the Progressive Democrats in 2001 - the year before a €6,300 ceiling was placed on donations - was above board.
The issue emerged in the Dail today when it was raised by Labour party leader, Mr Pat Rabbitte, who said Mrs O'Rourke had told the Seanad yesterday she had was "speechless" at information she on donations by Mr O'Leary.
The Aer Rianta Board is meeting in Dublin Airport today to discuss the legislation to break-up the State-owned airports operator.
Last night a spokesman for the company said the board had recently agreed a 10-year business plan and said he would not make any comment until after the meeting.
It has been reported that the board claims its was not consulted on the legislation before its publication.
Yesterday the Minister for Transport,
Mr Brennan, published the State Airports Bill to break up the three Aer Rianta airports at Dublin, Cork and Shannon.
A new state agency the Dublin Airport Authority will replace the Aer Rianta board.
There will be no transfer of assets from this authority to Cork and Shannon until they produce business plans which meet the approval of the Minister for Finance, Mr McCreevy, and the Minister for Transport.
Under the Bill says this cannot happen before April 30th next year but it is understood the transfer process could take up to 18 months.
It is likely that the process will lead to a confrontation with the existing Aer Rianta board and its chairman, Mr Noel Hanlon.
The plan has run into further objections from the unions with the SIPTU president, Mr Jack O'Connor, claiming the Government was pressing ahead with was "ideologically driven and ill-conceived" legislation.
