With the success of RyanAir and EasyJet in Europe, I believe that Skybus was trying to emmulate both of them. Take a look at what RyanAir charges and what "frils" they don't have. And they have been wildly successful. A combination of oil and questionable leadership probably lead to their failure. Just like EOS, MaxJet, and a few others, just a bad damn time to start an airline.

But on the other hand, RyanAir pays very nicely.
