Looking at the offers on the aer lingus website, it seems cheaper to book two one way flights, taking advantage of their US$ offers (presumably aimed at Americans). For example, Boston to Dublin on 28 April is $276 (€175). If you book in Euro you will pay €235. The savings are even bigger on other routes / dates.
Have they some way of restricting the US$ offers to US residents only?
thanks
