What part of pro-rate is so tough to understand? SkyWest sets the ticket prices. SkyWest does all the advertising, pays for all the fuel, and the ground handling. Delta, United, American supply the ticketing and the connection status to mainline flights. In return, said mainline reaps a guaranteed profit (and connections) for absolutely no risk. The risk is entirely on SkyWest's shoulders. SkyWest Airlines made $31M last quarter and it wasn't because the pro-rate flying portion of the operation is losing money. Quite the contrary.
