Mostly in and out of Atlanta with some trips that flow in and out of Detroit and MSP. Just look at the Skywest route map for Atlanta for Delta and it will answer you question. Orlando is to bad lots of options. Southwest can be better then Delta. Best part of Orlando you can get to any base direct and pick up trips to have different flying. Last week I picked up two trips out of COS for some West Coast Flying. Try doing that at smaller regionals. Best of Luck
