Passenger numbers have grown by 1% to 22.7m at Irish airports over the past year, according to results published today by the Dublin Airport Authority (DAA).
International traffic grew by 2% but domestic air travel within Ireland continued to experience significant declines, the company said.
The DAA also reported earnings before interest, taxation, depreciation and amortisation (EBITDA) of €160m in 2011, an increase of 9%.
Turnover was effectively flat during the year at €557m, while Group profit declined by 9% to €30m due to the impact of higher interest and depreciation charges.
Costs were reduced by 1% to €275m, despite the inclusion of a full year’s operation of the Terminal 2 facility at Dublin Airport for the first time.
“In the context of a weak economy, both in Ireland and our key overseas travel markets, the Group had a satisfactory financial performance last year,” said DAA Chairman Pádraig Ó Ríordáin.
“We doubled terminal and boarding gate capacity at Dublin and simultaneously reduced our overall costs to 2005 levels, which is a significant achievement,” according to Mr Ó Ríordáin.
“We will continue to take further steps to reduce our cost base."
Earlier this month the Government announced that Shannon airport was being transferred from the remit of DAA to that of Shannon Development.
Today's figures show a 93% drop in domestic passenger numbers at Shannon over the past year.
Overall Shannon saw a decline of 7% percent in its passenger numbers - down to 1.6m - while its domestic passenger numbers fell from 25,064 in 2010 to just 1,649 last year.
Mr O'Riordáin said the first priority for Shannon airport will be a targeted business plan to address the huge drop in domestic passenger traffic.
