There are no CX discounted fares even from ethnic agencies. Your best bet might be to buy your tickets FROM BKK to SFO return. Since its your own company, you may justify doing that. However, please note that the fares from BKK to North America all went up by about 10-15% effective 6 Sep 2002. The average fare from BKK to West Coast USA is about THB 125,000 or thereabouts. Flights are booked in D class. CX's J class fares (booked in J) have gone through the roof!
