RegionsAir operated under a code sharing agreement with TWA and American Airlines to provide flights to communities as AmericanConnection from Lambert St. Louis International Airport, and as Continental Connection from Cleveland Hopkins International Airport. RegionsAir ceased all operations on March 8, 2007, and furloughed all of its employees a month later.

RegionsAir was known as Corporate Express Airlines from 1996 to 1998, and then Corporate Airlines from 1998 to 2004. Operating as Corporate Express, it flew for Midway Airlines providing feed until their first shutdown in 2001 and also flew for TWA as Trans World Express out of St. Louis. When TWA merged into American Airlines on December 2, 2001, Corporate began operating as AmericanConnection continuing to provide flights to communities from Lambert St. Louis International Airport. At that time, the airline was run by Chuck Howell, who became the president at Great Lakes Airlines. The airline changed its Corporate name to RegionsAir in May 2004 to end confusion with similarly named airlines. RegionsAir began another code sharing alliance with Continental Airlines as Continental Connection in 2006 with a hub at Cleveland Hopkins International Airport. RegionsAir had been the air service provider for many small communities as part of the federally subsidized Essential Air Service (EAS) program. On October 7, 2005, Viva International, an aviation holding company, issued an irrevocable Letter of Intent to Purchase RegionsAir for an undisclosed sum, but nothing ever became of the LOI. In March, 2007 the Federal Aviation Administration (FAA) grounded the airline, saying there had been problems with the airline's training and certification program.

On October 19, 2004 Corporate Airlines Flight 5966 crashed on approach to Kirksville, Missouri. Thirteen people died and two were injured. The National Transportation Safety Board (NTSB) has determined pilot error to be the cause of this accident. On March 2, 2007, the local Airline's FSDO office, FAA officials in DC, and the airline got into a disagreement over wording in the airline's training manuals. The airline voluntarily ceased scheduled operations until the items could be clarified. FAA officials found no discrepancies when they went over all pilots records. In the end, about 35 of the airline's flights were canceled that Saturday. On March 8, 2007, at 4:36pm the FAA again grounded RegionsAir due to discrepancies in the airline's training procedures for line check airmen. As a result of this second grounding within one week, several regional airports serviced by RegionsAir announced intentions to replace the airline with other regional carriers.
