While I think it would be better long term for the pilots to have all the groups merged, I'm also confident from what you posted that Jerry and Chip have all the legal room they need to prevent such a merger from taking place.

Your contract mentions air carriers and their affiliates, but it never specifies that if an affiliate is the legal purchaser that lists at their parent company must also be merged. It only specifies that whoever purchases XJT or is purchased by XJT must merge lists. In this case that means ASA and XJT.

One of the things you will learn as part of the SkyWest Inc. family is that Jerry and Chip don't do anything without doing their due diligence, having a long term plan, and considering all the contingencies. They aren't the short sighted and inept managers that plague this industry.
