The government has extended the lockdown till May 3, which was to end on April 14.
Most of the airlines had chalked out their plans to resume services from April 15 in expectation that the lockdown will be lifted.
"We may, however, have to extend the period of 'leave without pay' for further term, if so required," the airline said.
An official, however, said about 10 per cent of the 5,500-odd employees, who are crucial for certain tasks even when there is no operation, continue to work and will be paid partial salary.
We are hopeful that the skies will reopen from May 4 and we will resume operations in a phased manner. Meanwhile, the airline also said it is working towards building its ability to scale up operations in the new environment and market conditions that would emerge going forward.
Open bookings only after govt decides on starting flight services: Aviation Minister to airlines
Civil Aviation Minister Hardeep Singh Puri on Saturday said airlines are "advised" to open bookings only after the government takes a decision on starting domestic and international commercial passenger flight services.
"The Ministry of Civil Aviation clarifies that so far no decision has been taken to open domestic or international operations," he wrote on Twitter.
