to form one enclosure. The original terminal building was then converted for use as offices for general aviation, the FAA, and the U.S. Weather Bureau. The 1973 terminal building had its last flight take place on January 13, 2013. In 2013, a new passenger terminal was built directly in front of the 1973 terminal. This new building solved several problems of the previous terminal building, including that the tails of parked airplanes extended too close to the runway due to FAA airspace changes made after the building's completion. This terminal building has restrooms and concessions beyond the TSA security checkpoint, something the previous terminal lost when screening processes were put in place after 9/11. The first flight to leave the new terminal was on January 14: United Express Flight 5292 to Chicago O'Hare. On October 30, 2015, the new terminal was named for the late U.S. Representative Jim Oberstar, who represented the congressional district in which the airport lies from 1975 to 2011 and helped secure funding for the facility before its 2013 opening. A 370-stall parking ramp with skywalk connection to the terminal was completed in fall 2014. On May 23, 2019, American Airlines began twice-daily service to Chicago O'Hare International Airport. American ceased operations into Duluth in April 2020, citing lackluster demand. In 2020, the airport received a $5,246,844 federal grant via the CARES Act.
