1986–1987: On October 1, 1986, Northwest Airlines completed its merger with Republic Airlines. Northwest flew only one route from VPS: nonstop to Memphis, a Northwest hub which was also a former Republic and Southern Airways hub. By September 1987 Northwest had four non-stops a day to Memphis with stretched McDonnell Douglas DC-9-30 and DC-9-50s. Later Northwest would reduce its schedule from VPS to three daily DC-9s nonstop to Memphis. No other airline flew jets into VPS until Valujet/Airtran appeared in the 1990s.
