I submitted a feedback via TK.com about one way redemption.
I cannot find any flights out of YYZ (AC, UA, LH) - I expect no availability on AC Rouge, AC Express, UA express, just like before.
I did find DPS-SIN-PEK that I recently booked with Aeroplan. I am surprised to see both SQ and SQ/CA flights are available for 20K Y and 35K C. No YQ.
I thought TK didn't allow mixed carrier on 1 award ticket?
