My complaint is the layover in SYD when connecting tfrom PER to LAX/JFK using the red-eye. I recall almost 6 hours waiting time.
PER-SYD-JFK-SJU = 13570 m
The earlier SYD-LAX flight might save a bit of waiting but would still be a pain.
Consider PER-HKG-YYZ or PER-NRT-DFW-YYZ for much more social flight times. (and maybe even prices)
Happy wandering
