Update - Successfully booked my 1st ever miles redemption on United.
BLR - SIN - ICN and back for 1.05L miles + 11.5k taxes for Both Economy via Singapore airlines .
Didn't have enough miles for Business. But I'm glad that this is happening on miles being used.
I am not sure if its a good value or not but i had a plan for South Korea, going there makes me feel happy as being a K Drama fan.
