The loss-making carrier has already received more than Rs 26,000 crore under the bailout package announced by the former UPA government in April 2012.
"We have sought restoration of the equity infusion in Air India and have written to the government last week in this regard," a senior airline official said.
The official, however, did not disclose the amount of the funds the airline was looking at.
The UPA government had approved a turnaround plan under which Air India is to receive a total equity infusion worth Rs 30,231 crore up to 2021, subject to meeting certain performance thresholds.
Amid fund crunch, during which Air India also had to defer its staff salaries, the airline borrowed Rs 6,250 crore from various banks between September last year and January this year for working capital requirements and other needs.
The carrier, which has a debt burden of about Rs 50,000 crore till March last year, had been receiving about Rs 3,000-4,000 crore equity infusion on an average per fiscal from the government till FY14. However, after that the amount was gradually reduced.
For 2018-19, the airline has been allocated Rs 650 crore in view of its now failed disinvestment plan.
The government had proposed to offload 76 per cent equity share capital of the national carrier as well as transfer the management control to private players, besides complete sale of its low-cost arm Air India Express and its entire stake in 50:50 joint venture AI-SATS.
