WT+ to CW on the 9th of June evening flight to PVG, Booked the ticket last minute, only full price ticket available in J so I settled for Y+, was very pleased to get my first upgrade to J in 10 years of intensive flying (got a lot of Y to Y+ on CX on regional hops),
After discussing with one of the FA, 20+ were upgraded on this flight (my guess is that it was mostly from Y to Y+)
