Outsourcing, will it become the new airline trend?

One of the remedies that Northwest Airlines is attempting to implement into their bankruptcy case is the outsourcing of flight attendants, ground crews, and pilots occupations if they do not agree to revise their current labor contracts. This proposition to the courts if passed will eliminate hundreds of millions of dollars in debt for the company due to cheaper labor rates and intern eliminate thousands of currently held jobs. Personally, I do not believe this process is ethically sound on the airlines part. It seems to me as a devious way to terminate the contracts they cannot pay and force labor rates in the airline industry down more than they already are. The MSNBC article reported the fact that if this proposition receives the courts approval for Northwests request many other airlines are likely to follow suit.
