Rule No. 1 is you have to search segment by segment to get a true R reading. Otherwise the domestic connector (which is almost always R0 these days) will zero you out.

To find TPACs with available R, search HKG-EWR. HKG-ORD. HKG-SFO. Same with NRT, except you can add in IAH, DEN, and LAX. TPE-SFO. ICN-SFO. HND-SFO. If you don't mind a China routing, you could also search from PEK, PVG, and CTU.

Monday to Wednesday are the easiest days to upgrade the eastbound routing.

If you don't find anything today, search again tomorrow. And the next day. And the next . . . .
