IAG, the owner of British Airways and Spanish carrier Iberia, sank into a 1.68 billion euro ($1.8 billion) net loss in the first quarter due to coronavirus fallout, it said Thursday. The loss after taxes in the three months to March contrasted with a slender net profit of 70 million euros a year earlier, IAG said in a statement, as it also revealed that chief executive Willie Walsh will finally be replaced by Iberia boss Luis Gallego on September 24. jwp/rfj/wai
