Why does everyone assume that all of their flying will be forever out of CMH? There is nothing to stop Skybus from flying (for example) MCI-BUR once they get enough aircraft. Also if you look at their website they view most of the state of Ohio as their catchment area; they have distances from CMH to CVG and CLE amongst other cities. Lastly never underestimate the willingness of people to go out of their way for a low fare. Just look at Ryanair and Frankfurt Hahn; who the heck had ever heard of that airport before Ryanair started their and now it is a good sized airport in terms of traffic despite being a good distance away from a major city. Yes I do know that FRA is much larger than CMH but the same basic idea is there and I would not be surprised at all to see Skybus establish other bases outside of CMH.

When it comes to having no phone number; I am not holding my breath to see that one as a permant move. What I can see happening is them not using a toll free number and charging lots more $$$$ when they people try and book over the phone.
