Afternoon from Melbourne

I am coming over to the states this November, and something I wanted to do in life was to see a space launch, and there is not many left. Anyway, at the moment one is on the 14th November at Kennedy Space Centre. I have the following questions.

-Does WN fly direct through to ORD? If so, what aircraft type. I see plenty of $99 base fares there, and even if there is a few stopover's included which is good for a first timer to the States.
-Does any other LCC fly to ORD? Or is their a Full Service Airline that has low prices on the route..?

Just after any help you could give me.
Cheers
