PEK- SIN - CA - A359

SIN - PER - SQ - 787

PER - SIN - SQ - A359
SIN - IST - TK - 777

YUL - YYZ - AC

There are two AC flights that I am not crazy about since the fees are high, but I've locked down these routes for now and I am looking for availability and will most likely change some of the segment if other awards open up. If you go out of YUL, TK usually have good availability and I like TK since if your flight has a layover more then 9 hours, they put you up in 5 stars hotel or you can do a free tours ect. Plus the new lounge is super nice.

You can also look at Yow to bkk - to Per as an alternative if there's not much availability via SIN. I've seen some YYZ - to TPE - SIN with Eva, that has super cheap tax that you can also look at. Others may have other insight but that's what I found. Hope that helps.
