Interglobe Aviation Ltd, which runs India’s largest airline IndiGo, reported a quarterly loss on Thursday as Covid-related travel restrictions continued to dent its operations. The global aviation industry has been among the worst hit by the pandemic and related travel restrictions. The airline said it expects third-quarter average seat kilometres (ASKs) to be around 60% of its ASKs for the same quarter a year earlier. “We are slowly but surely stair-stepping our way back to normal capacity,” Chief Executive Officer Ronojoy Dutta said in a statement.
