Northwest Airlines was a major U.S. airline which existed from 1926 until 2010, when it merged with Delta Air Lines. At the time of the merger it had a total of 320 aircraft with seven on order. It was also the last U.S. airline to have a dedicated cargo fleet and routes. Northwest, unlike Delta, operated a mixed fleet of Boeing, McDonnell Douglas, and Airbus aircraft. The Boeing 757 was the only type of jet common to the pre-merger fleets of both Delta and Northwest. The Northwest fleet was integrated into Delta's fleet on December 31, 2009. The airline ceased operations and merged into Delta in 2010. Most of Northwest Boeing 747 fleet was sent to Delta which had retired all of its own 747s before the merger. ==Pre-merger Northwest Airlines fleet== As part of a major fleet renewal program, Northwest introduced a simplified new paint scheme and logo in 2003, emphasizing its callsign (NWA). The airline replaced its McDonnell Douglas DC-10 airliners with the Airbus A330. Its first Airbus A330-300, used initially for European flights, arrived on August 6, 2003. Northwest also flew the longer ranged and slightly shorter A330-200 on some trans-Pacific flights, within the Orient, and on some trans-Atlantic routes. The majority of Northwest Airlines' flights between North America and Europe were flown in Airbus A330s. (Northwest became the largest owner and flier of A330s in the world.)〔(Northwest Airlines Becomes Largest Airbus A330 Operator In The World ) (Official Press Release: October 18, 2007)〕 Northwest Airlines also possessed the youngest trans-Atlantic fleet of any North American or European airline. Northwest Airlines also began flying reconfigured Boeing 757–200 airliners on some of its European flights carrying fewer passengers. Northwest was one of only two passenger airlines in the United States to fly the Boeing 747-400, with the only other one being United Airlines. (There are several airlines in the United States still flying the Boeing 747 like United Airlines and Delta Air lines. Northwest was looking for manufacturers to discuss the replacement of their 100, 110 and 125 seat McDonnell Douglas DC-9 aircraft, with an average age of 35 years.〔(U.S. Airlines Put Off Buying New Planes )〕〔(Using Old DC-9s Pays Off for Northwest )〕 In January 2008, Northwest advised its pilots that the airline planned to cut its fleet of 92 DC-9s to 68 DC-9s by the end of 2008. Northwest stated that pilot jobs will not be reduced, as they would hire approximately 200–250 pilots by the end of 2008.〔(Northwest Airlines To Reduce DC-9 Aircraft ) (USA Today: January 22, 2008)〕 On April 23, 2008, due to soaring fuel costs from $1.85 in the first quarter of 2007 to $2.77 in the first quarter of 2008, Northwest announced that an additional 15 to 20 aircraft would be removed from its fleet by the end of 2009. The grounded aircraft included ten or so DC-9s, with the balance of the 15 to 20 being a mix of 10 Boeing 757s and 4 Airbus A320s. The airline's average fleet age was 18.5 years by the end of 2009.〔(【引用サイトリンク】title=Average fleet age for selected airlines )〕 The Boeing customer code for Northwest Airlines was 7x7-x51 (i.e. 747-451). The Northwest Airlines fleet consisted of the following aircraft as of August 2009:〔(Northwest Airlines Corporate Fleet Information )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Northwest Airlines fleet」の詳細全文を読む スポンサード リンク
