State-run oil companies issued a final warning to Air India asking them to make monthly lump sum payments by October 18 or else they would stop fuel supply at six major domestic airports. In a letter sent to Air India, the three oil PSUs — Indian Oil Corporation Limited, Bharat Petroleum Corporation Limited and Hindustan Petroleum Corporation Limited — stated that the arrears have not been reduced due to non-monthly lump sum payments as promised. In August, three fuel retailers said that Air India’s outstanding fuel bill had reached Rs 5,000 crore, which had not been paid for almost eight months. On August 22, Indian Oil Corp, Bharat Petroleum Corp Ltd and Hindustan Petroleum Corp Ltd halted supply of fuel to Air India at six airports at Kochi, Mohali, Pune, Patna, Ranchi and Vizag due to non-payment. However, after the intervention of the Ministry of Civil Aviation, he resumed fuel supply on 7 September.
