The Irish government's 2015 National Aviation Plan ruled out privatization of Dublin Airport because of its strategic importance to the Irish economy. We are revising our assessment of the link between Irish airport operator DAA PLC and the Irish government to strong from limited. We're also revising our view of the likelihood of extraordinary support for DAA by the government to moderately high from moderate. We are therefore raising our long-term corporate credit rating on DAA to 'A-' from 'BBB+'. The stable outlook reflects our view that DAA's credit measures will remain broadly stable over the next couple of years, and that Dublin Airport will continue to be owned by the government.
