We found a cheap deal a couple of months ago from SFO-SYD which we booked on Virgin Australia (flight is operated by DL). We are based in LA so we then bought a one way ticket from LAX-SFO on Virgin America (in retrospect, should have done it on DL).

My question is
Will Virgin America check us in, print boarding passes, check luggage through for the entire journey?
OR
Will I have to get to SFO and recheck in for that segment?

Has anyone tried this or ANY thoughts are appreciated?
