State-run Air India owes the Airports Authority of India (AAI) Rs 1,200 crore while debt-laden private carrier Kingfisher Airlines owes Rs 235 crore, AAI Chairman VP Agrawal told reporters.
"The sector is under a lot of stress, and we can't take a unilateral decision on one airline. Grounding flights (of Kingfisher) will impact revenues and reduce connectivity further," he said.
AAI is responsible for managing the civil aviation infrastructure in the country.
