You must not be paying attention. UAL did not renew mesa's agreement because Sky West wrote a $118 million (plus) check. Express Jet agreed to provide the service at below cost AND gave up 20% of the company in warrants.
You don't know what ExpressJet bid. Those numbers are confidential. And Inc did not loan UAL that much. You can speculate all you want but in the end, that is all it is, speculation.
