Vijya Mallya-owned private carrier, which is on the edge of bankruptcy with its flying licence suspended, had committed that the salary dues till May would be paid by Diwali.
As the management failed to meet its promise, employees representatives had threatened to chalk out action plan if they did not receive the May salary by November 17.
The regulator DGCA had suspended Kingfisher's flying licence on October 19 till further orders after a lockout and its failure to come up with a viable plan to revive the airline.
The bankers to Kingfisher have also warned the airline to arrange for more capital by November 30, though Mallya has denied any deadline issued by the lenders to his company.
Kingfisher has accumulated losses of about Rs. 9,000 crore as on September 30.
