This is high on my wish list as well, since SAN is a focus city and LAX is a hub, it would make sense. However, I use UA and DL often for this routing and those e175s are very rarely booked more than 50-75% full. So I understand why AS may be fearful of running this flight, it has zero O/D pax traffic on it. As an ex-United 1K, we have watched UA go from almost hourly service to the 2-3 a day that run at the same times as the DL flights. They have even consistently run 737 equipment on it. Oh well…
