Leaving China at short notice - with maybe 36 hours between phoning BA and going - I didn't have time to decant the stuff I didn't want - I packed it all.
I was living in Shenzhen, and went to the Walmart and bought a few suitcases. Packed to the silly point of popping - 31.6kg per bag - I checked them in at Shekou Sea Port in the Emerald Queue without issue.
On arrival into HKG - peak Covid - I was greeted into the F lounge where, as arriving from China I was 'clean' and full service ensued, for 14 hours.
To this day, how 4x suitcases, and me on an original Y ticket scored such a luxury can put no value on OneWorld.
I am sad, however, to soon drop ranks and no longer be a part of it.
