I would be interested in anyone here having more information on this as well. I just finished a mileage run from SFO - SIN and back.
I have done this for the past three years and since SIN is kinda expensive, I started taking cheaptickets.com flights to southeast Asia.
such as HKT, BKK, SGN .. etc.on SCOOT and this year on Vietnam Airlines.
Getting the additional miles would be great if the price remains low for some of the SFO-SIN tickets.
I did SFO-SIN-SFO for 750 bucks this year(Nov 18-27th).
