No. They were destroyed when they could not compete against other regionals. Both airlines had contracts that paid their employees well. DAL and United pulled their flying. Funny... while I remember DAL and United pilot cheering them on when they fought for the contracts I don't remember them doing anything when their companies pulled the flying.
"United Airlines entered bankruptcy protection in December 2002. At that time United Airlines contracted a consulting firm, Bain, to renegotiate its regional partners contracts. Atlantic Coast Airlines employees and management went though a significant cost reduction program to remain competitive as a United Express carrier. Presented with overwhelming competition from other regional airlines Atlantic Coast Airlines and United Airlines were unable to negotiate a mutual agreement. At that time Atlantic Coast Airlines continued to honor its 10 year contract with United Airlines. Expecting that United would be unable to honor that contract, Atlantic Coast Airlines developed an alternate business plan.After announcing plans to part with United Airlines, Atlantic Coast Airlines' significant cash position made it a prime target for a takeover attempt. Mesa Air Group launched an attempt at a hostile takeover in the Summer of 2003, engaging in what some allege were significant U.S. Securities and Exchange Commission violations. At the same time the employees of Atlantic Coast Airlines organized a grass roots effort to avert the takeover attempt. Within a few months the stock purchase plan was removed by Mesa.
On November 19, 2003, Atlantic Coast Airlines announced that it would become a low cost carrier under the name of Independence Air. Its status as a United Express carrier ended on August 4, 2004, and its status as a Delta Connection carrier ended November 2, 2004. Operations as Independence Air began on June 16, 2004. On January 5, 2006, Independence Air ceased operations.
On March 10, 2006, Northwest Airlines purchased the DOT Operating Certificate of then-Independence Air with the intent to use that certificate to form a new regional subsidiary. The result was Compass Airlines, which began service using Embraer E175 jets in August 2007."
COMAIR was an owned subsidiary of DAL. DAL pilot just stood by and watched as they were purged.
