Ha, no wonder I see that weird G3 line on my sample bookings for next year
I'm okay with it, only because at least HKG limits YQ

although it still adds up for 4 paxs ... $30 x 4 = $120 @@
Per person - sample flight in J into/out of HKG (destination)
Hong Kong Air Passenger Departure Tax $19.80
G3 $26.40
