SUG AMS-JRO question
I am flying RT MSP-JRO via AMS in Sept 2013. Using a SUG cert I was able to get upgrades on the DL segments MSP-AMS and AMS-MSP. But no upgrades are available for the KLM flights, AMS-JRO-AMS. The JRO-AMS seg is actually already sold-out in first/bus.
How can I optimize my changes of getting upgraded on the AMS-JRO-AMS flights?
