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.
call in tonight some interesting things: since my original flight AC YVR-LAX is AC economy, rep said my new flight YVR-SFO UA has to be economy even though UA Busi is available, and during the calls LHR-WAW LO seats is gone

I ask to route through AMS but rep said have to route through LHR

.......so in the end they can't put me on flights 3 days earlier instead put me on flights 2 days earlier
