Jets for Jobs (J4J) says that the Express carrier can add regional jets outside scope limitations if they put a percentage of mainline furloughed pilots in the cockpit. US Airways came to Skywest with their Jets for Jobs about a year ago and we voted it down. Not sure how the CHQ contract is, but with Skywest, there was going to be some percentage of Captains and FOs from the furlough ranks that get "stapled" to the bottom of Skywest's seniority.
Basically mainline gets scope relief while the pilots get their jobs back.
