I have scheduled a trip to HKG and SIN this July. I was getting quotes between $1,500 and $2,200 on United.com, Expedia and Orbitz. Then I realized these sites did not allow me to book Q, V and W fares, although they were available (search under expert mode on United.com). In the end, I called my consolidator agent and purchased W fare for less than $1,000. There is no minimum stay requirement for my ticket ( I am staying 2 days in HKG and 3 days in SIN)
