Book Taiwan air ticket problem, already booked with passport

1. No, just take your passport to go through check-in procedures and security checks. The Taiwan Pass is only used when entering Taiwan. <br/>2. If you really want to change it, you can only refund the ticket and buy it again, and you cannot change the certificate.

You can check in with your passport, but the procedures are very troublesome, especially at the airport on the other side of the return journey. So contact the airline to change the documents. This happened to me, and before the pass came out, I fixed the ticket with my passport (I handled it on behalf of Ctrip). After the pass came out, I called Ctrip to change the certificate, but the name, including pinyin, could not be changed. The document must be changed 48 hours before departure. This is what Ctrip said. It was a few years ago and I can’t remember clearly.
