I was wondering about SFO-DUB being a codeshare possibility; from the above, it looks as if I would have to get to LAX and originate LAX-SFO-DUB. Maybe a cheaper r/t AA or AS from OAK, SFO or SJC nested to a r/t from LAX. Hmmm. SFO-LAX-DUB is less complicated, but at 500 EQM / 506 EQP SFO-LAX, it's worth thinking about if the fare is right.
