Northwest Airlines has its major hubs in Amsterdam, Tokyo, Detroit and Minneapolis/St. Paul. Considering its presence in these bustling cities it should come as no surprise that it has over 1,200 departures every day. Thus, it is one of the top five airlines in the world. It will continue to grow with its partnership in SkyTeam. Together they can provide service to over 160 countries. One of the added benefits to flying with Northwest is its WorldPerks frequent flyer program.
