Delta will be just fine. Delta is unlikely to sell ASA or Comair anytime soon. We are the only parts of the company that are showing a profit.
Could they sell us? Who in the business has the cash to buy us? Who would invest $3 Billion in airlines right now?
At some point they could spin us off. If they did, they would still retain a controling interest in us, and we would likely still fly their code.
I was hired at ASA after being furloughed from another airline. It was the best decision I have ever made in this business. Comair is probably a better place to go right now, because they are getting the growth, and ASA will not hire for a while.
