Pierre, SD, USA / DRGNews May 3, 2021 12:05 PM SkyWest Airlines is appealing the US Department of Transportation’s decision to award Denver Air Connection (and its subsidiary Key Lime Airlines) a federal contract to provide commercial air service to airports in Pierre and Watertown starting July 1. In a letter to the US DOT dated April 28, 2021, SkyWest Market Development Director Greg Atkin writes the selection was a “puzzling move” because Denver Air’s proposal didn’t meet several of DOT’s five mandatory selection criteria. He says SkyWest believes it is in the best interest of Watertown and Pierre for the DOT to issue a re-bid.
