China Airlines review by Rajiv 2015-08-24

If you plan to you use an upgrade certificate on China Airlines, be prepared for a MAJOR runaround. They gave me dozens of excuses and even lied that their certificate couldn't be used to upgrade from Premium Economy to Business. I finally used it to upgrade from Economy to Premium Economy. But I had to physically go into their office, tell them that I wouldn't leave their office unless they honored the upgrade (and that they could have me arrested to get me out) until they finally caved and applied it. Just be warned that they have a different standard of business ethics.
