Just to add, the certificate that was going to be used for DC Air was Potomac Air, which was created using Dash-8s flying out of DCA. After the merger was called off, it was shutdown after 9/11. It would later be dusted off and planned to be used for MidAtlantic, first with CRJ’s to get the certificate going and later planned for use with the newly ordered Embraer 170. Eventually it was decided MidAtlantic would just use the Airways certificate and it became an airline within an airline. One that would use express pay rates, express livery, but used the USAir call sign, mainline payroll etc.
If the UA/US merger would have gone through, the plan was to use the Potomac certificate to create DC Air as you mentioned. Initially using 737s from the merger, but eventually AA was negotiated into the plan. They would own 49% of DC Air and would provide wet leased F-100s.
Interesting times.
