Northwest Airlines has taken delivery of the first of 16 757-300s, marking another milestone in the largest fleet renewal program in the carrier's 75-year history. Northwest will use the efficient 757-300 as a replacement for its fleet of DC-10 Series 40s, substantially reducing fuel and operational costs on high-demand domestic routes. Additional deliveries of 757-300s are scheduled later this year and in 2003. Northwest's first 757-300 is also the first such Boeing model to be delivered with Pratt & Whitney PW2000 engines, having earned certification from the U.S. Federal Aviation Administration last month. With the delivery to Northwest Airlines, the 757-300 has entered service with three major North American carriers in the past 12 months.
