For what it’s worth, did this last week and today.
Suppppper easy.
Delta agent was waiting for my TPE-NRT flight, escorted me to a bus (with only me as passenger??) and I was through security and into SkyClub in maybe 8-10 minutes? It was wild.
So easy and pleasant.

On the inbound pdx-nrt-TPE, it was easy busy ride to terminal 1.
No security check at all.
China Airlines lounge is a bit hard to find. But it was fine.

I hope figure pdx-hand-tpe will have China airlines as connection.
Great connection, great airline. Really happy with this trip and how DL made it easy.
