Well like you said, its not a hub so...
Also there's been rumblings of new airport talk in KC but the way this city moves, and as broke as it is, and in this economic climate, I wouldn't expect anything for 20-30 years (at least). I wouldn't be surprised to see analysis that would show a positive return on a new build, given how they're sitting on so much dead space with today's set up/ right now.
