Taiwan non-rev
 

Looking to fly non-rev NRT-TPE-NRT using a ZED on another carrier. According to the U.S. department of state we need a confirmed return ticket out of Taiwan in order to get in:

"U.S. citizens seeking entry as tourists or visitors are required to present a valid passport that will remain valid for the period of intended stay. You must also possess a confirmed return or onward air ticket." and "Taiwan authorities can deny a visitor entry if they do not have the appropriate travel documents for their onward destination."

Does anyone have experience with non-rev travel into and out of Taiwan?

Just have your return ticket (ZED back to NRT) printed out & on hand and your company ID with you.
Ive gone through a few countries before that required a confirmed ticket for proof of return and haven't had any issues.
