DUBLIN— Aer Lingus (EI) plans to cut up to 500 jobs and lower its flying capacity as part of a wider restructuring. The Irish flag carrier will also end four routes from Dublin Airport (DUB), serving Denver International Airport (DEN), Harry Reid International Airport (LAS) in Las Vegas, Minneapolis-St. Paul International Airport (MSP), and Split Airport (SPU) in Croatia.
The airline blamed rising costs and a difficult economic climate, pointing to higher oil prices linked to the US-Iran conflict. The plan follows a profit warning from parent company IAG, which also owns British Airways (BA) and Iberia (IB).
Job Cuts Hit Pilots, Cabin Crew, And Head Office
Aer Lingus told the Irish Times that the reductions could affect 70 pilots, 140 cabin crew, and 290 roles at its head office at Dublin Airport. The proposed cuts represent about a quarter of wider employee costs, mirroring an earlier move that removed a quarter of senior management roles.
The restructuring is expected to lower overall flying capacity by 6%, affecting both long-haul and short-haul services. Aer Lingus currently operates more than 100 routes connecting Europe and North America.
Aer Lingus chief executive Lynne Embleton said the carrier’s accelerated transformation aims to ensure the airline is “a strong investment case and able to weather the turbulence in our industry.”
Aer Lingus Cuts 3 US Routes
The routes being cut all depart from Dublin. They serve Denver, Las Vegas, Minneapolis, and Split. Three of the four are transatlantic services, and each recorded weak load factors before the decision.
Dublin To Denver Ends In September
As disclosed by Ishrion Aviation, the final DEN-bound service will depart DUB on September 28. Cirium Diio data shows the route, covering 3,817 nautical miles (7,069 km), was already scheduled to pause then. The difference is that it will not return in 2026.
Aer Lingus launched the route in May 2024, the first scheduled service ever between Ireland and Colorado. It operated on a summer-seasonal basis, almost always with the Airbus A330-200. Frequency rose from four-weekly in the first season to six-weekly in the second.
The added capacity reduced demand per seat. US Department of Transportation (DOT) figures show the load factor fell from 73.7% in 2024 to 63.9% in 2025. In the 12 months to March 2026, just 64.1% of seats were filled.
Dublin To Las Vegas Ends In December
Aer Lingus began flying to Las Vegas in October 2024 on a thrice-weekly, winter-only basis. The carrier will resume the route on October 2 using the A330-200 and A330-300, but it will now end on December 3 rather than in late April.
In the 12 months to March 2026, the route carried 33,448 passengers with only 71.3% of seats filled. December 2025 was the weakest month at 59.8%, followed by January 2026 at 62.8% and November 2025 at 69.3%.
Dublin To Minneapolis Ends In October
The Minneapolis route is the only one of the three US services flown with narrowbody equipment, the 184-seat Airbus A321XLR. It operated year-round, while Delta Air Lines serves MSP-DUB only during the summer. Aer Lingus’ final flight will take place on October 24, the last day of the northern summer under IATA slot seasons.
The route recorded loads below 50% in six months between April 2025 and March 2026. February 2026 was the worst at 30.0%, the carrier’s second-lowest US result from Dublin that month behind Seattle-Tacoma International Airport (SEA) at 28.1%.
Fuel Costs And The IAG Profit Warning
IAG issued a profit warning in May, citing high jet fuel costs and supply chain disruption made worse by the Iran conflict. The London-listed group said it expected to spend about €2 billion (£1.72 billion) more than planned on fuel this year.
IAG chief executive Luis Gallego said the company was “managing the uncertainty” caused by the fuel price increase by “taking the necessary action on yields, costs and capacity.”
He added that all airlines “need to increase fares to mitigate the impact” of higher fuel, which accounts for about a quarter of their costs.
Aer Lingus Targets Stronger Margins
Aer Lingus is aiming for an operating margin of 12% to 15% in the medium term to attract further investment.
That compares with its 2025 operating margin of 11.1%, which trails the more than 15% achieved by fellow IAG carriers British Airways and Iberia.
