The XJT vacation rules allow them to get far more days off than the ASA pilots. You aren't the first ASA pilot I've talked to that thinks their system is better than the XJT pilot's. Fact is the XJT pilots have huge leverage with their vacation rules and line bidding. It beats out most mainline groups using PBS as well.

If you really don't understand the leverage regional pilots hold, you can join all those other groups voting in concessions for pointless reasons. Good luck replacing the ASA and XJT pilot groups with any pilots other than ASA and XJT pilots.
