Ireland's Aer Lingus announced Wednesday that it would begin flights between Philadelphia and Dublin on March 25, a week after St. Patrick's Day.

The year-round service will operate four times a week — on Monday, Wednesday, Friday and Sunday — between Philadelphia International Airport and Dublin, the capital of the Republic of Ireland.

"We are very pleased to welcome Aer Lingus to PHL and look forward to offering more nonstop, year-round service to Dublin," said Chellie Cameron, the Philadelphia airport's CEO.

Aer Lingus' Chief Operating Officer, Mike Rutter, said, "We are proud to continue to deliver on our promise to grow our trans-Atlantic network and further strengthen Dublin Airport as a leading gateway to North America, and we are looking forward to welcoming guests from Pennsylvania."

From Dublin, Aer Lingus passengers can connect to 21 destinations in Europe and Abu Dhabi. The first Aer Lingus flight will arrive at PHL from Dublin on March 25. Aer Lingus will use Boeing 757 aircraft on the route.

Flights will depart Dublin at 1:50 p.m. and arrive at PHL at 4:15 p.m. The Dublin-bound flights will leave PHL at 5:30 p.m. and arrive in Dublin at 5:10 a.m. the next day local time.

American Airlines now serves Dublin from PHL with year-round nonstop flights.

PHL offers service to 37 international destinations, including 16 capital cities.
