"More than half a million Northern Ireland residents used Dublin Airport last year, a 15 per cent increase on 2011, according to new figures from the Dublin Airport Authority (DAA)

The growth in northern business was far in excess of the average at Dublin Airport in 2012, as total passenger numbers at the airport increased by 2 per cent to 19.1 million last year.

“Dublin Airport’s business from Northern Ireland is booming,” said DAA Public Affairs Director, Paul O’Kane. “Last year 521,000 Northern Ireland passengers travelled through Dublin Airport, which is equivalent to almost 30 per cent of the population of the North.”
