Flight
Dublin International Airport will be the best airport to fly into! There are lots of direct flights from all areas in the US. Dublin International Airport is only about 6 miles outside of downtown Dublin and only about 12.5 miles to Luttrellstown Castle!
Travel Note
Transporting from the Airport to Dublin City Center: Taxi – easiest and there is a rank at the departures level at T2. We found just grabbing a taxi right from the airport was the easiest option! Uber – operates great in Dublin! It will actually call you a registered taxi which is amazing, so no getting in unmarked cars :) There is also, https://www.free-now.com/ie/ which is basically the same thing as Uber! Coach – Aircoach is a great comfortable service that drops near some of the hotels www.aircoach.ie
