Garuda started the court-led restructuring process on Dec. 9, after a vendor petitioned the court over unpaid bills. It has repeatedly requested more time to negotiate restructuring terms and verify $13.8 billion of claims against it.

The state-controlled airline has said the claims were bigger than the $9.8 billion it has in its books and that it would seek to cut its total liabilities to $3.7 billion under the process.

Martin Patrick Nagel, one of the curators, in a text message to Reuters said the new deadline was June 20.

It was unclear how many claims Garuda still has to verify and the carrier did not immediately respond to a request for comment. As of March 14, claims worth $9.72 billion were yet to be verified and another $885.5 million was in dispute.
