A spokeswoman for Ryanair has said the airline has not yet heard from Aer Lingus following the board's refusal to proceed with an extraordinary general meeting of shareholders to discuss the Shannon controversy.
Aer Lingus said this morning a letter had been sent to the shareholder.
Ryanair, which owns a 29.4% stake in Aer Lingus, had requested the meeting to discuss the airline's withdrawal of the Shannon to Heathrow route.
Campaigners in county Clare seeking a reversal of the decision are to meet the Minister for Transport, Noel Dempsey, next Wednesday to discuss the matter.
The Shannon Connectivity Alliance is supporting Fine Gael's call on the Government to use its 25% shareholding in Aer Lingus to hold an EGM.
The demand follows yesterday's decision by the board of Aer Lingus to reject Ryanair's request to hold such a meeting to discuss the airline's withdrawal of its Shannon to Heathrow service.
Aer Lingus said that the holding of an EGM could constitute a serious breach of both Irish and European competition law.
A spokesman for the Fine Gael leader, Enda Kenny, said the Governmenrt still has primary responsibility for the situation that has develped at Shannon.
He said the Government cannot wash its hands and walk away from the issue and all shareholders should be allowed an opportunity to express their views.
However, a spokeswoman for the Minister for Transport, Noel Dempsey, said the decision was a matter for the airline's board.
The Atlantic Connectivity Alliance has said it is backing Fine Gael's demand on the government and said it will continue with its own campaign to have the decision reversed.
