Delta Air Lines is the largest carrier at MinneapolisSt. Paul International Airport (MSP). The carrier took the title after merging with Northwest Airlines, which had the most extensive route network from the airport. Although Delta made some changes when it inherited Northwests fleet and operations, the carrier continues to be a major component of MSPs passenger traffic, whether domestic or international. Many of Deltas international routes from its hub at MSP are handled by Airbus widebodies.
