My new theory. Delta waits for 9E to decimate the contract. They let the training involved in the senriority order furlough to cause drastic cuts in the contract to pay for it. They transfer the rest of comair's planes to 9e, the now cheapest carrier in the industry. they park a bunch of 50 seaters, transfer as many 70 plus seat rj's to 9e as possible and work on putting ASA into ch11.

I hope i'm completely wrong.
