Checked online the AC flight been pushed back 1 hour so left me 8 mins to transit in LAX now 
I guess I can call in ask any flights 155k miles I want? (better transit from SFO/DEN since it's a UA hub?), actually I would prefer to travel 3 days earlier do you think that will ask too much or worth a try? Just want to be prepared before call in.
If they won't change the date I'm thinking of wait for last-minute transpacific business class space https://princeoftravel.com/guides/wh...m-award-seats/, do you know if United still release these seats nowdays?
You can call in and ask for anything that you see when you do a miles search on United’s website, regardless of the number of miles. Moving travel by three days probably won’t be allowed unless that’s the only reasonable flight combination (and even then you might get pushback). And, yes, I’d avoid LAX to the extent possible; you’ll have more UA options through ORD or SFO.
UA may well offer last-minute award space, but I don’t really see how TPAC space helps you very much.
You’re unlikely to be able to do anything like YVR-SFO-NRT-FRA-WAW without paying a bunch of extra miles.
