Northwest Airlines Corporation · Eagan, MN United States

For now, you can still fly Northwest -- at least until the logos on the planes change to "Delta." Northwest Airlines, which was acquired by Delta Air Lines for $2.8 billion in late 2008, transports passengers and cargo to about 240 cities in North America, the Asia/Pacific region, and Europe. Its US network includes locations served by regional carriers flying as Northwest Airlink. Northwest's fleet includes about 320 jets; regional partners operate another 200 aircraft. The acquisition by Delta created the largest airline in the world by traffic. Once the integration of the two carriers is complete, Delta will operate a fleet of about 775 aircraft and serve more than 375 destinations worldwide. To read the full description, subscribe now.
