AA has had a variable relationship with SJC over the years - it buys airlines that fly there, then dismantles the route structure, builds up a hub, then cuts back the flights. Although I don't fly AA, the last time I flew out of SJC, from the time I left downtown SJ (for business) to the time I actually walked into the terminal, after dealing with long term parking and so on, I could have actually driven to OAK, parked in the economy lot, and walked into terminal 1.
