I signed up for travelocity's fare watcher, so they email me whenever certain fares are at a good price. I'm in the east bay and so I have it notify me for sj, sfo, and oak. Lately (in the last few months) the prices have been around $200. You could book it but see first if you can get a refund if they go lower. I know how you feel about whether or not to book so early. Makes me nervous to not get a good price. We are going on United miles, because the price is over $400 for when we are going (president's weekend), but if our days were flexible they would have been about $200. Good luck.
