I was in the Wing April 5 then April 12 and I didn't find it that empty ( F section). It was even a bit "crowded" on April 12 (I was on CX261).
Business on the other hdans seems empty - well, I've never really paid attention before, but he Long Bar was deserted - not a single passenger, while F was "busy " (all areas of the F lounge had some pax, the restaurant was busy, the cabanas + showers were all taken).
