This involves a large aircraft order, thousands of new jobs and several new flight routes, according to the newspaper.
The investment plan extends over the next five years and will make SAS a significantly larger airline.
"SAS is making one of the most significant investments in our history," writes the airline's CEO Anko van der Werff to the newspaper.
Bloomberg has previously reported that SAS is about to purchase 15-20 new aircraft, but Anko van der Werff has not confirmed this to Berlingske.
SAS is holding a press conference in Denmark at 10 a.m. today.
