I was looking (through my wife's nonSE Aeroplan account) at award availability for YOW-YYZ on May 16, and return on May 19 - in both economy and business class. The KVS tool suggests that there are several flights with award availability in one or both classes of seats on those 2 days; the Aeroplan search engine shows that there is literally zero availability (taking account both classic and classic plus availability!) on both days! Should I presume (as indicated in the other thread: link:
