Looks like Skybus has finally started selling tickets. One of there start up cities is Kansas City. I just looked on there website, and i can fly from MCI-CMH for 40 dollars total. I have heard that you have to pay for everything though, like soda, food and they are even gonna sell watches and perfurmes.
I think Skybus could have an effect on Midwest if they start focus cities in MCI and MKE, and MKE could be very possible
