The Air India official, however, said the flight operations of the airline are currently unaffected.

Oil marketing companies (OMCs) on Thursday afternoon stopped the supply of fuel to Air India at six airports due to non-payment of dues, said a senior airline official.

However, he said the flight operations of the airline are currently normal and unaffected.

The airports where the fuel supply was stopped by the state-owned OMCs at around 4 pm are Cochin, Visakhapatnam, Mohali, Ranchi, Pune and Patna, another official of the national carrier said.

Air India spokesperson said,"In the absence of equity support Air India cannot handle the huge debt service liabilities."

"Our financial performance, however, this fiscal is very good and we are moving towards a healthy operating profit. The airline despite its legacy issues is performing very well," he added.
