Actually, the Delta law suit is for a breach of contract.

Hawaiian sued because they felt that Mesa used confidential information provided to them when they were considering purchasing them, but instead started Go.

Aloha is sueing them for predatory pricing.

Mesa tried to sue an Aloha pilot for publicly stating slander against the company. (This forum should be plenty of bad publicity.)

It sounds like only the lawyers are turning a profit at Mesa.

So, if you want to work for Mesa, be a lawyer, not a pilot.
