United Airlines will increase its nonstop flights between Dublin and the United States for the summer 2025 season, boosting seat capacity with larger aircraft and adding frequencies on existing routes. In total, the airline will offer five daily flights and more than 7,300 weekly seats between the U.S. and the Irish capital, representing an increase of 40% compared to the previous summer.
The Chicago O’Hare-Dublin route will increase its capacity by replacing the Boeing 757-200 with the Boeing 787-8 Dreamliner, which seats 243 passengers: 28 in Business Class, 21 in Premium Economy, 36 in Economy Plus, and 158 in Economy. In this segment, United competes with American Airlines and Aer Lingus, which also operate wide-body aircraft.
Meanwhile, the Washington-Dulles-Dublin service will add an additional flight, operating up to two daily frequencies. Both will be operated with Boeing 757-200, which offer 176 seats: 16 in Business Class (lie-flat seats), 42 in Economy Plus, and 118 in Economy. On this route, United competes exclusively with Aer Lingus, which also uses single-aisle aircraft.
During the summer season, United Airlines will operate two daily flights between Newark and Dublin using Boeing 777-200ER and 757-200 aircraft. The 777-200ER has a capacity of 276 passengers: 50 in Business Class, 24 in Premium Economy, 46 in Economy Plus, and 156 in Economy.
