Thanks guys. At first, I didn't realize a Y/B has no affect on flights from the US to Asia, and thought if I bought a Y/B ticket, I'd get automatically upgraded to business class fro the SFO to TPE route. Since the contract pays for coach but not business on this trip, I spent alot of time looking for a good Y/B flight under $3,500. What a waste of time, didn't realize it was useless. Thanks for your time guys
