Once India's biggest private carrier, Jet stopped flying in April 2019 after running out of cash, owing billions to lenders and leaving thousands without jobs.

Jet said the grant of an air operator certificate by the Directorate General of Civil Aviation "was the final step in a comprehensive regulatory and compliance process involving several procedural checks for the airline's operational readiness."

The airline had said in June that the National Company Law Tribunal (NCLT) approved a resolution plan submitted by a consortium of London-based Kalrock Capital and UAE-based businessman Murari Lal Jalan.
