I'm planning to fly to SYD and KHI and am able to get a routing with 100K as follows and $1100 in taxes and fees.
AC 103 YYZ YVR (14h 15m connection)
AC 33 YVR SYD (Stop)
SQ 232 SYD SIN (22h 20 min connection)
SQ 976 SIN BKK (2h 10min connection)
TG 341 BKK KHI (Stop)
TK 709 KHI IST (10h 35min connection)
TK 1911 IST ZRH (11h 20min connection)
AC 879 ZRH YYZ
I opted for the long connection times, however can these be extended further as stopovers for a whole 24 hours or more. Looking to stop longer in SIN and IST.
Upgrading to J takes the costs up to about $1200 more to buy the extra points.
