Pretty good deal indeed, can also try on routing thru HKG by CX (more miles, and, probably better service?)
with Stopover in HKG (NOTE HKG tax added so just below $1900)
Note that:

MUST COMMENCE NO EARLIER THAN 1201AM ON THE FIRST SUN
AFTER ARRIVAL AT THE FIRST FARE BREAK OUTSIDE COUNTRY OF

OR - TRAVEL FROM LAST FARE BREAK OUTSIDE COUNTRY OF FARE
