Pre-covid, TPE was basically a pseudo 767 base. Unfortunately, that is no longer the case. Personally, I doubt that it will ever be the case again. All of our Asia ops have basically consolidated in ICN.
The 767 still has a regular route that starts and ends in ICN. Every weeknight it goes ICN-TPE-NGO-ICN. We have 747s go to TPE for letter checks, but I'm not sure that they do any actual cargo flights in or out of there.
