May 2026 is proving to be a fertile period for Aer Lingus’ route network, with the Irish flag carrier launching no fewer than five new routes from its main hub atDublin Airport (DUB) this month. This growth is indicative of a wider era of expansion that also saw it begin flying to Raleigh–Durham (RDU) in the US state of North Carolina in April 2026, with another new route to Tours in France set to begin on June 6 of this year.
