Have to disagree on this - hub-and-spoke contribute to poor aircraft utilization. Aircraft which could be turned around in 30-40 minutes may stay at the hub for an hour or more. 20-30 extra minutes on the ground may not seem like much but it does add up during the course of a day. Also, if there is a disruption at a hub airport due to weather, blocked runway, or whatever, then the aircraft utilization goes down even more and the entire system is screwed up because of one airport.
