The flying licence of the beleaguered Kingfisher Airlines, suspended by the aviation regulator, expired on Monday.
It is learnt that DGCA officials sought additional details from the airlines on how it would fund its revival plan submitted to the aviation regulator for resuming its flight operations.
The licence was due for regular renewal by December 31.
Last week, the airline had submitted an application for renewal of its Scheduled Operator's Permit (SoP) to the Directorate General of Civil Aviation (DGCA).
The airline has not operated its flights since Oct 1, when it grounded its planes owing to a strike by employees over unpaid salaries.
Thereafter, the DGCA suspended Kingfisher's scheduled operator's permit Oct 20, as the company failed to provide a convincing plan to resume operations.
