This is a little off topic, but some major airlines have on site kiosk check-ins at Taoyuan.
I flew to the states two weeks ago via EVA and the employee at the front of the queue for check-in told me, if I had a US passport, I could self check-in.
I did as he suggested. Kiosk check-in took me 2 minutes and I got on the line (in which I waited zero seconds in) for bag drop-off and was another 2-4 minutes at the counter. The employee checked my luggage weights and double checked that the luggage had no connecting flights. Done and done.
