Yeah Sky Bus can have those $10 dollar flights because 80% of the time they are cancelled and your stuck in airport's for 2-3 days.
Just seems like if you really need a cheap ticket, that's the way to go, but other carrier's like Midwest, US Airways and Delta are a much better avenue to persue as far as air travel and also noramlly very reasonable also. Just my $ .02 cents. :-)
