Trying to book a multi-city in June NAS-YYZ-stopover-YYZ-YUL late the next day in FLEX. AC.com One way won't offer a flight late enough on the YYZ-YUL leg and multi city won't offer FLEX, even is asking for economy flexible pricing returns economy lowest.

Could do 2 one ways, but would prefer single ticket on the off chance the daily NAS-YYZ is cancelled to get protection the next day (an 18:30 departure out of NAS makes rerouting somewhat challenging at that hour)

GF pushes to the AC website but to the search page and not the booking/priced out page

Anyone know any magic tricks to force FLEX or am I gonna have to call in?
