Aer Lingus is cutting four routes to the United States and scaling back several European services as part of a wider effort to reduce costs and improve profitability, a move that could place up to 500 jobs at risk across the airline.

The Irish carrier said it will discontinue its Dublin-Las Vegas, Dublin-Denver and Dublin-Minneapolis routes later this year, while its Dublin-Seattle service will operate on a summer-only basis beginning at the end of October. The changes are part of a broader restructuring plan that will also reduce the airline's annual flight schedule by about 6%.

The decision comes as airlines continue to navigate higher operating costs, including fuel expenses that have remained volatile amid geopolitical tensions in the Middle East. Carriers across Europe and North America have continued to reassess network capacity and route profitability in response to changing demand patterns and cost pressures.

Denver service will end after Sept. 28, Minneapolis flights will cease after Oct. 24, and Las Vegas service will conclude after Dec. 3, according to details published by Irish Travel Trade News and confirmed by multiple Irish media outlets. The Seattle route will transition to seasonal operations after October, Irish Travel Trade News reported.

Aer Lingus is also making changes to its European network. The airline will discontinue flights between Dublin and Split, Croatia, after Sept. 29 and move Frankfurt, Malta and Hamburg to summer-only operations beginning in early November.

The restructuring could affect as many as 500 employees across Aer Lingus' headquarters, cabin crew and pilot divisions, according to The Irish Times. The airline has said the measures are intended to stabilize operating margins and support continued investment in the business.

Aer Lingus has not publicly disclosed which positions may be affected or whether redundancies will be voluntary or compulsory.

The airline, which is owned by International Airlines Group, has expanded its transatlantic footprint significantly over the past decade, leveraging Dublin's U.S. preclearance facilities to attract travelers heading to North America. Before the announced reductions, Aer Lingus served more than 20 destinations across the United States and Canada.

The route changes follow a challenging period for the airline. Aer Lingus was forced to cancel hundreds of flights in 2024 due to an industrial dispute involving pilots, disrupting travel plans for tens of thousands of passengers. The company has since focused on restoring operational reliability while managing rising costs and increased competition on key routes.

Industry data show airlines across Europe have become increasingly selective about long-haul capacity deployment, particularly on secondary North American destinations. Several carriers have adjusted schedules in recent months as travelers continue to prioritize major hubs and leisure markets, according to Reuters.

Aer Lingus' parent company, International Airlines Group, has previously highlighted the importance of maintaining profitability across its portfolio of airlines, which also includes British Airways, Iberia and Vueling.

Passenger traffic through Dublin Airport has remained strong despite broader economic concerns. More than 32 million passengers passed through the airport last year, according to figures from Dublin Airport, underscoring Ireland's continued importance as a transatlantic gateway.

Aer Lingus said the network adjustments are part of an effort to align capacity with commercial priorities as it seeks to strengthen its financial performance.
