Check fare rules. There may be new restrictions on the fare class for the AMD-SIN segment.
Personally, I would trade 5 hours and 40 minutes of scheduled flight time in Y for almost 18 hours in J. I fly cross country in the US in Y (roughly similar distance) a few times a month.
It's an overnight flight. I wouldn't.
