Another downfall of both IDE and XJT was that their contract partners (UA and CAL, for instance) didn't take kindly to the new competition. UA killed Indy with price matching out of IAD and CAL most likely put a lot of pressure on XJT with a new contract for their CoEx flying. Chances are, any regional trying to start up even remotely competitive businesses will face the wrath of the very companies bankrolling the effort.
