It shocks me to, but if people can get the train for a lot cheaper and it gets them into the centre of Dublin and all of the waiting about the airport and maybe delays. Then there is a new toll road opened which bypasses the traffic at Drogheda (THANK GOD CAUSE THE TRAFFIC WAS BAD!) which shaves about 45 mins of the time at least for a measly 1.50 Euros per car. Also when getting closer to the airprot there is a road which just takes you direct to the Car Parks and the terminal. I live in Lisburn which is near Belfast and I did the jouney in 2 hours for over 100 miles. Thats brill!
