The thing that jumped out at me was that most of these (sans EJ) are how unhappy the work groups either are - or have been recently.
1. ASA - bitter dispute with new parent company SkyWest
2. ComAir - Recent crash - fate uncertain - DAL shopping for buyer.
3. AE - It's an AMR company - of course the employees are unhappy.
4. Mesa - is anyone really surprised they are on this list?
5. Express Jet - I'm a little surprised - I am sure CAL would rather delay/cx one of these flights then a mainline flight.
6. US Air - East pilots are PO'd - how much effort do you think they are making to make sure there flights leave on time?
7. AA - Again, no surprise that an AMR company has unhappy employees.
8. UA - Work groups took a beating in the last BK. From what I can tell from riding on the JS (not much) morale seems really low.
9. DAL - BK took a toll on morale - maybe they will be off the list next time if things continue to improve
10. AS - again bitter employees. Locked out ramp agents, bitter contract talks with pilots.
I don't think it's a coincidence that the groups that have generally happier employees (Southwest, Frontier, JetBlue, SkyWest, CAL) are missing from the list.
For me, the only surprises are the inclusion of Express Jet and the exclusion of Northwest or any of their express carriers.
