DAA is responsible for the management, operation and development of Dublin, Cork and Shannon airports. It also looks after domestic and international retail management and airport investment. Last year its airports handled in excess of 30 million passengers.

DAA is investing €2 billion in facilities at Dublin Airport in order to improve the customer experience. Customers can already begin to see the benefits of the Transforming Dublin Airport programme: Pier D - delivered October 2007 and Area 14 - delivered May 2007. These new investments will allow Dublin Airport to handle up to 35 million passengers per year.
