Delta Air Lines Inc. and Northwest Airlines Corp. are in talks on a possible merger, the Wall Street Journal reported on Wednesday.

The newspaper said representatives of the two carriers, which are No. 3 and No. 5 in the United States respectively, have met regularly for weeks discussing a possible link-up after they both emerge from bankruptcy.

The two airlines have been restructuring in bankruptcy since September 2005. A Northwest spokesman declined to comment. Delta officials were not immediately available for comment.
