I will check this @ work tomorrow. It really should only be the base fare you should be concerned about. The taxes that apply to the ticket are local airport taxes. If you have booked with a tvl agt and have at least 1 CP segment, you can have them send it to CP for pricing.

If agent is on Sabre, have them send it to QCP10/4 and if they are on Apollo, have them send it to QEF/1. Have them note :Attention agent TUK. I don't recall any taxes (like GST) that would apply for international travel originating in Korea, Thailand or India, but will verify this to be certain.
