Mumbai : Kingfisher top brass has appeared before DGCA to explain large-scale flight disruptions which continued for the fourth consecutive day with cancellation of 23 more flights on Tuesday.

Kingfisher CEO Sanjay Agarwal and other officials met DGCA chief EK Bharat Bhushan and gave a revival plan of their disrupted flight schedule.

The major air route of Mumbai-Delhi was the worst-hit with maximum cancellations and clubbing of flights.

The carrier faced fresh problems on Monday with 34 pilots quitting and a large number of staff being put on notice.

The resignation of the pilots have taken the total number of those who have quit to about 80 since last October, industry sources said.

Kingfisher has been suffering from a severe cash crunch that has culminated into the Income Tax authorities freezing its bank accounts last week on grounds of non-payment of tax dues.

Civil Aviation Minister Ajit Singh had on Monday ruled out any bailout of the airline.

The carrier on Monday cancelled 30 flights including those to Bangkok, Singapore, Kathmandu and Dhaka, leaving hundreds of passengers stranded at various airports across the country.

Concerned over the sudden cancellations and passenger inconvenience, aviation regulator DGCA had summoned the airline’s CEO and top officials to appear before them on Tuesday to explain the large-scale disruptions in the operations and the reasons.
