Reno Air has a hub in Reno, but it certainly is nothing like the size of American's hubs. Reno is a city of less than 100,000 people, and Reno Air only has about 35-40 departures a day there. SJC failed as an AA hub earlier, but I feel that it may work now. People are sick and tired of flying into SFO. SJC is also in a more central location. There are many more people living in a 30 mile radius around it, then SFO. San Jose now has half a dozen or so really great museums, and lots of nice restaurants, and hotels. It is now much more of a tourist destination, all though the primary crowd is still business.
