On September 17, 2025, Irish carrier Aer Lingus announced plans for its largest-ever transatlantic summer schedule for 2026. Aer Lingus has significantly grown its transatlantic network with the addition of ten new routes in the past four years, thanks in part to the arrival of four new Airbus A321XLR aircraft. Aer Lingus services from Shannon to Boston will also increase by three weekly flights to ten in peak summer. Beginning in April 2026, the new route will bring the total number of routes Aer Lingus operates to North America to twenty-six. “The year-round route will operate up to five times weekly on Aer Lingus’ new Airbus A321XLR aircraft.
