Thoughts of a late night knitter

All I want to do is book online a flight from Chicago to Columbus. Cheap tickets com only includes European countries on it's drop down menu and American Airlines direct you to their worldwide sites, and there isn't one in Australia. It's aggravating.

I can book with Southwest airlines no trouble, but they leave from Chicago Midway airport and I'm flying in to O'Hare. Can anyone tell me how long it takes to get from one airport to the other? I'm losing my window to book a cheap flight *wails*.

I'll keep looking at the other sites I guess - but why is it so hard? Australia is an American ally and has even signed a dumb free trade agreement with them....
