Such a shame - I made GGL during the 25% reduction and have kept it every year afterwards but it's been a pure hobby with some fun trips across the OW network, including the crazy AHU - CGK trip.
I usually hit about 3500 TPs from mainly ex EU fares with QR or AA.
Would be interesting to see what my previous runs would earn me in the new system - I can't really workout where it will land with the differences in %miles for some and revenue for others (including AA sharing base price I see, even ex-EU). Any takers lol...
Probably academic though if GGL needs 80% booked through BA (if that is true)...
