I need to be at the airport this Friday morning for an 8.50am check - in. I'll be coming from the sticks in Wexford up the N11 and intend heading out the M50 just before the Loughlinstown roundabout and over the West link - how long should I give myself to make the Airport from the turnoff for the M50? I have done this journey several times but never at rush hour on a Friday morning.
