It seems like TPAC in general will perform much better than usual, due to the overall capacity decreases and, in particular, the significant limits on US-China flying.

The years leading up to COVID saw a glut of seats on the Chinese carriers, a lot of which were low-yield connections around Asia.

So the drag on US-China capacity is a boon for the rest of Asia, increasing the chances of success on these new flights and making the performance of existing flights to SIN, HKG, TPE, etc. even stronger.
