I keep reading these rumors on this forum that Mesaba and Compass will be sold, but I have not read any evidence to this. NWA will not be selling Mesaba anytime soon. In a few years maybe. Compass was a creation by NWA pilots from what I have gathered. The NWA rep at the joint NWA/DAL merger presentation said Mesaba and Compass will continue business as usual.
Also no one at XJ talks about Compass much. Not really interested that much because there are so many things going on at XJ right now.
