"Creditors filed two complaints against the restructuring plan, which the court accepted," the airline said in a statement.

"The Central Bankruptcy Court will suspend the review to allow planners and creditors to clarify the issues."

Earlier this month, Thai Airways creditors' approved a restructuring plan before it was sent to the bankruptcy court for review.

The plan seeks to restructure 245 billion baht ($7.83 billion) of debt through payment extensions, interest waivers, and debt-to-equity conversions.

The airline was in difficulty well before the coronavirus pandemic grounded flights across the globe, booking losses nearly every year after 2012.
