Aer Lingus has announced plans to cut up to 500 jobs and reduce its flight network as part of a restructuring programme aimed at improving profitability amid rising costs and stronger competition.
The Irish airline said the proposal could affect 290 positions at its Dublin Airport headquarters, 140 cabin crew roles and 70 pilot positions. Aer Lingus currently employs around 6,000 people.
Alongside the workforce reductions, the airline plans to reduce its overall flight capacity by 6% through the removal of underperforming routes and seasonal adjustments to several services.
The company said the measures are being introduced in response to a difficult economic environment, increased competition on transatlantic routes, higher fuel costs and a first-quarter 2026 loss of €103 million (£87 million).
Aer Lingus said customers affected by the route changes will be contacted directly and offered alternative travel arrangements or refunds.
The restructuring will begin from late September 2026 and continue into the summer of 2027.
Among the changes, flights from Dublin to Denver will end after September 28, while services to Minneapolis will cease after October 24 and flights to Las Vegas will stop after December 3. The Dublin-Seattle route will become a summer-only service after October 24.
Within Europe, the airline will discontinue its Dublin-Split route after September 29. Services to Frankfurt, Hamburg and Malta will also become summer-only operations beginning in November.
The revised network will reduce the need for aircraft during the 2027 summer season, with Aer Lingus planning to operate two fewer Airbus A330 aircraft and four fewer Airbus A320 aircraft during peak travel periods.
The airline said the restructuring is necessary to strengthen its financial position and support future investment.
“The changes are essential to support required improvement in its operating margin, which is needed to underpin future investment,” an Aer Lingus spokesperson said.
The company added that consultations with employees and unions will focus on limiting compulsory redundancies and exploring ways to reduce the overall number of job losses while securing the airline’s long-term future.
Aer Lingus said it is targeting an operating margin of between 12% and 15%, which it believes is necessary to attract investment and support future growth.
Chief Executive Lynne Embleton described the restructuring as part of a broader transformation designed to strengthen the airline over the long term.
She said the programme is intended to position Aer Lingus as the preferred airline connecting Europe with North America while continuing to make a significant contribution to Ireland’s economy.
The announcement comes as airlines across Europe continue to face pressure from higher operating costs, intense competition and changing travel demand. Aer Lingus said improving efficiency and productivity would allow it to invest in its future network and remain competitive in the international aviation market.
The proposals are subject to consultation with employee representatives before any final decisions are made.
