A senior official at the disinvestment-bound national carrier said that the DGCA has already renewed the Scheduled Operator Permit (SOP) of Air India's international budget arm Air India Express recently.
"In the case of Air India, it has applied to the DGCA for renewal of its flying permit and the documents pertaining to renewal are being processed," the official told Press Trust of India.
The DGCA has already renewed the SOP of Air India Express, he added.
As per the DGCA, Air India's flying permit is valid till June this year, while Air India Express SOP was to expire on 21st of this month.
The Civil Aviation Ministry has sought Expression of Interest (EoI) from potential bidders for a 76 per cent stake sale in loss-making Air India as well as divestment of two of the carrier's subsidiaries, a move that is being opposed by the airline's unions on grounds that it would result in massive job losses.
On March 28, the ministry came out with the preliminary information memorandum on Air India's strategic disinvestment.
In a letter to prime minister Narendra Modi on Wednesday, eight employee unions of Air India had raised serious concerns about the disinvestment and have sought an alternative revival plan.
In the letter, signed by representatives of the eight unions, they have also flagged the possibility of job losses in case of privatisation.
Air Corporation Employees Union, All India Service Engineers' Association, Air India Employees Union, Aviation Industry Employee Guild, Air India Aircraft Engineers' Association, All India Aircraft Engineers' Association, Air India Engineers Association and United Air India Officers Association have written the letter.
Together, these unions represent more than 10,000 Air India employees.
