And as a corollary, LAN probably fills the front better with paid passengers on AA codeshares at an AA hub than at a UA hub. Which would mean that only on the flights from the UA hub would they forecast tons of empty seats (if they don't have miles redemptions use up some of them).

But your Profile lists your location as SJC. I'm confused. Isn't it easier to drive from SJC to SFO than to get to LAX (in any manner) from SJC???
