I didn't know that. But nobody want to go to Skywest, envoy, Xjet or a place with a long upgrade. You know, because being the CA quicker is the best path to a major (sarcasm).

At envoy if you're on RSV and don't proffer or call to verify your schedule, they call you at 12:00am and give you a 10am reserve avail period, which is basically a long call.
