How does being a wholly owned subsidiary mean you should get reduced benefits?? In the end, being the employee of a subsidiary of delta should be the same as being an employee of delta. Of course the mainline guys are ok with this, all excuses aside, it doesn't matter if it's right or not, just that it's in their benefit. Maybe if you stepped up for once and demanded the same benefits and salaries for those at the wholly owned companies, there would be less of an incentive to outsource flying in general... The arrogance of some mainline guys on this board is astounding...
You may have a legitimate argument with contract carriers, but they should still have priority on their own metal...
