Meanwhile, the Denver Post is following the United story carefully, and the pilots seem ready to prove again why unions shouldn't run businesses. UAL wants to start a lower-cost regional carrier, something that's worked well for the other airlines, and which may allow them to compete with the Frontiers and the ATAs of the world. Naturally - the pilot's union, which is responsible for much of the lopsided labor structure to begin with - opposes it. Most pilots I know love to fly, but somehow, I don't think they're going to be able to afford their own 737s, even when they go on the auction block.
