Aer Rianta has said it is "sick and tired" of claims by Ryanair that facilities at Dublin airport are inadequate and that airport charges are too high. Aer Rianta chairman, Mr Noel Hanlon said Ryanair was now paying the same airport charges as it did in 1994, even though it now carried twice the number of passengers. Mr Hanlon said two recent meetings between Aer Rianta and Ryanair to discuss charges and facilities at the airport, were scuppered by Ryanair's chief executive, Mr O'Leary.
