Agreed - some of the transcon services are almost impossible to use (either one direction or the other) from Northern Cal. But I would guess that its not in the AS business model to seriously market those flights to us - of course, they will sell them. They are designed for O/D travel. When you think about a market like OAK/IAD, which is very competitive now, AS has no incentive to sell you an OAK/SEA/IAD trip because not only to they sell it cheaply, but they have basically filled up an OAK/SEA seat for free, and can't sell it to another pax (esp. in light of reduced capacity in some west coast markets).

And so those are my thoughts, which may have no basis in fact, rationality or sanity
