It's a perfect example of the Hub Paradox; people from regions spend longer traveling to the dominant hub than they might actually spend on the flight.
But the new entrant airlines don't dare break from the hub, because that's where the passenger catchment is. But the catchment is only there because the airlines make it a hub...
