Just booked online:
SIN-x/CPH (SQ 772ER) - IST (TK A320) - YYZ (TK 77W) - x/TPE - x/HKG (BR 77W) - SIN (SQ 772)
I get the new SQ Business Class seats on the 777-200ERs, TK's and BR's 77W aircrafts. ^
125K for J.
Taxes $127.66
I'll probably change on my way back to different dates.. but for now, I'm glad.
Balance remaining 17 miles.
Thank you all for your help !
