BKK-SYD on TG 475 in C. Ticket booked on the TG website. That's why I thought it was odd. Now and again OTAs have problems with transmitting numbers during ticketing, but seldom when you book on the airline's website itself. In the last few months I've used this TK FF successfully booking tickets on the websites of SQ, LH, JP, and BR - so it's not a FF number problem from my side....in the process of swapping away from UA to TK as my main FF program, as I won't be doing many internal flights in the US anymore and USD 550 at the UA 1K rate for United Club membership is absolutely exorbitant.
