The company, which also owns Iberia, Aer Lingus and Vueling, said passenger capacity was reduced by 94% from late March as Covid-19 spread around the world and most of its aircraft were grounded.
IAG said it hoped to operate about 50% of its pre-crisis passenger capacity during the rest of 2020 but added these plans “are highly uncertain and subject to the easing of lockdowns and travel restrictions”.
