What's the reason? Those guys have a lot to go through and the Frontier purchase is not yet finalized. I can't answer why they are or are not doing anything but the world isn't out to get you regardless of what that ALPA propaganda wants everyone to believe. When only looking out for yourself it's easy to throw things around and wanting everything now but what if it were the other way around and Midwest had purchase 4 other airlines. Do you think they'd be all ready to go so quickly? Look at US Air and what those guys had to go through. That was two. Here you have five. There's a lot to go through. What if this rush to arbitration makes something much worse happen then what was being planned? Once you cross that line you can't go back. What if the Frontier guys want RAH to hold off on Midwest so they can be part of the process? (just a what if again not saying it's the case I'm simply pointing out how it might be beneficial for everyone to show some patience)
