Whats so hard to understand? Together Delta, the non existent RAHs largest customer by traffic, along with American, UsAir and CAL are all chiping in to help RAH grow Frontier/Midwest into viable stand alone competition. They do this by replacing their own employees with those who have zero, nada, zilch commitment to their airlines and using properties maintained by the lowest bidder of the lowest bidder.

And all of the union lawyers of the unions whose contracts are being violated are too afriad to question a judgement from years ago.

It makes complete sense: sell your people, rent part time replacements, build your competition, profit in the short run.
