Umar Farouk Abdulmutallab will now get his mandatory life sentence on Feb. 16.
Federal Judge Nancy Edmunds said Friday that a Jan. 19 hearing will still take place so passengers who already had planned to attend can speak to Abdulmutallab in court that day.
The postponement gives Abdulmutallab more time to review a mandatory pre-sentence report prepared by the U.S. Probation Department.
He pleaded guilty in October to trying to blow up an Amsterdam-to-Detroit flight on Christmas 2009.
Abdulmutallab is acting as his own lawyer. The judge denied his request to grant him a new attorney to advise him.
