Aer Lingus' parent company, IAG, has reported a loss after tax and exceptional items of €5.6 billion in the first nine months of the year.
This is compared with a profit of €1.8 billion euros during the same period in 2019.
The airline group, which also includes Spain's Iberia and British Airways, reduced cash costs by 54% from previous plans, to €205 million a week. It said it wouldn’t provide profit guidance for the full year.
The group’s chief executive, Luis Gallego, said: “These results demonstrate the negative impact of Covid-19 on our business but they’re exacerbated by constantly changing government restrictions.
“This creates uncertainty for customers and makes it harder to plan our business effectively.”
