But if you want to do it within one day it is not really an option since the departure in SIN to BKK is quite late and would require an overnight stay in BKK, or a return with another airline.
I did this segment early this year, and yes the price was good with onboard service. However, looking at the miles that you get for this, was not really that good value, I remembered I had only around 3500+ miles only for the r/t with the Biz bonus. I don't think that there are any good discount for F-class, around 1000 SGD if I remember correctly for a return. But Biz and Y was good bargain for this short segment (considering service, which IMHO Swiss Rocks

)
I would have actually not mind doing this again, but yeah, a one day MR is this not possible due to their arrival and dep. hours.
