Thanks for the QF option. I'll check that out. My fare from SEA-SIN is $566 USD including taxes/fees so I would hate to have to pay more than that for the last 2 hours of my journey.

BTW, SQ has 4X daily service to DPS but the fare of $635 SGD is in Q class I believe, which doesn't offer any FF mileage. Unreal. Who does SQ think they are?
