Engaged Aer Lingus and the DAA have been engaged in talks with unions at the Labour Relations Commission to try and thrash out some type of an arrangement to plug the deficit. Aer Lingus has engaged in those talks, despite asserting that it has no legal obligation to put any more money into the scheme to shore it up. Ryanair has previously asked Aer Lingus executives to issue a statement assuring that no further funds would be put into the pension scheme without prior shareholder approval. At an investor conference in London in September, Aer Lingus chief executive Christoph Mueller said the pension scheme "is not our issue" and shareholders would have to approve any decision to put fresh cash into it. Ryanair has previously sought to force Aer Lingus to call an EGM to ask the board to give its "unequivocal support" for his comments.
