Got upgraded to J on HKG-DXB due to overbooking with BN 5, MPC Green. J was about 1/3 full only. On the way back, it was mostly Filipinos connecting to MNL and mainlanders with very very few local HKers (luggage belt was virtually empty on arrival). Had BN 4 but no upgrade. Was a bit surprised how low the BN got for a Green member.
