Norwegian Air secured a state aid package of 3 billion Norwegian crowns ($330 million) earlier this year after a debt restructuring but said last month it needed to secure more funding to get through the COVID-19 pandemic.
The government has changed the terms of the state guarantee scheme, the industry ministry said in a statement, without disclosing specifics.
"The changes we now propose are designed for the scheme to help more airlines than those who have already used it," Industry Minister Iselin Nyboe said in the statement.
The ministry was not immediately available for further comment.
