DAL has some pretty tight contractual provisions with Skw Inc (which includes SKW and ASA). Presumably SKW Inc DOES know how to write a contract without loopholes (unlike some fly-by-night operations).

They made a deal which included flying guarantees when SKW bought ASA. DAL has to be especially careful with ASA...even if they were unhappy with ASA, they would probably not attempt to get rid of them unless they had an airtight legal case.

Selling off ASA and then firing them could look like fraud in a courtroom...ie they misrepresented the value of the company they were selling because that value depends on a long-term DAL flying contract.

It is also unlikely that SKW managers would allow ASA performance to drop low enought to meet termination criteria.

Ultimately I don't think DAL is firing regionals just because they missed performance numbers once. I think DAL is using performance as an excuse to thin it's ranks, but it already knows who it wants to get rid of and SKW/ASA are probably not on that list.
