I have 4 SWU's expiring jan 31st and a total of 14 available.... Failed 3 times on HKG-LAX-HKG to use these J to F during 2017. It used to be easy to confirm C class, then that went away and now A class is getting hard also, just checked first 12 days of HKG-LAX (AA192). only 2 days have A availability but 10 have F availability. Just waiting when a new code is given to F upgrades so they can keep selling A.... The value of SWU's has really gone way downhill last couple years. In any case it's been an eye opening year. I still re qualified EXP but had some very good flights in BR's J class as well as SQ's F. Star lounge at LAX is just as good as the qantas lounge is.... No point in loyalty anymore, i will not just buy what ever is the most convenient schedule
