No flights to Dallas

I decided to follow the Flying Hamster of Doom's advice and check out studentuniverse.com. I tried finding a flight from Little Rock to Dallas. I sat there for about ten minutes and the page said it was still searching. I then tried finding a flight from Little Rock to Austin and immediately a list of flights popped up. I don't know how long I would have to sit there before the site would tell me if they found any flights to Dallas or not.
