For example, a SIN-JFK one-way upgrade from Y to J (Flex) is 135,000 miles.
If you did it SIN-DXB (65,000) and then DXB-JFK (90,000), it would cost you 155,000. Sometimes you have no choice because you may not be able to find availability all the way thru. By the way, these upgrade award levels are now officially outrageous!!!!
The oneway upgrade cost from SIN-DXB is 32.5k/42.5k , DXB-JFK is 45k/57.5k and SiN-JFK is 67.5k/85k
The rates you quoted are the round trip rates
