NEW YORK (AP) - Northwest Airlines says it has secured a new $500 million credit facility on the heels of one of the last remaining regulatory hurdles in its planned combination with Delta Air Lines Inc.

Eagan, Minn.-based Northwest Airlines Corp. said Wednesday the financing will consist of a three-year $200 million secured revolving credit facility maturing in 2011 and a $300 million facility maturing next year.

The financing was led by U.S. Bank. Citigroup and Morgan Stanley are co-lead arrangers and joint underwriters in the offering.

Earlier Wednesday, the Department of Justice cleared the way for the company's proposed combination with Delta.
