A quick Google shows lots of daily access to hubs. Unless you fly weekly, quick access to a local airport is much better than an hour and a half on the subway and air train to get to JFK (which has fewer destinations than the big hubs). That's not a real reason.
That isn't much help. The short flight from the local airport to the big hub will end up costing you more than the main flight from the hub to wherever you're going. Those short flights to regional airports cost a relative fortune.
