The story
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.
