The absolute worst airline in the world to fly known for bad customer service. They treat their passengers like crap and overcharge for lowsy service. You have to pay for just making a reservation itself, for a soda, pillows, blankets, to check in your bag and almost to even use the toilet. When asked by an employee to help you, they role their eyes and speak in a condescending manner. When your trip is over they stick a broomstick up your ass and tell you to beat it.
The carrier is the 5th largest in the U.S. and is headquartered in the Minneapolis-St. Paul area. It has major hubs in Detroit, Memphis and Amsterdam with focus cities in Seattle, Los Angeles, New York, Indianapolis, Washington DC and Boston.
Northwest Airlines is disgusting but I will only fly them when I have to.
