Correct - this particular one.

The pricing on AC.com is the same.

Other OTAs are showing pricing that is $50 higher than AC.com and FlightHub (the OTA I booked with). Must be some weird inventory thing going on

Anyway, FlightHub has graciously agreed to only charge me $25 per pax to cancel the booking. They are laying the blame at Air Canada's feet for not populating the fares properly in the GDS. So I'll eat the fees and just go and book on AC.com just like AC wanted me to in the first place.

EDIT: Just rebooked on AC.com. Same choices (economy standard both ways) and same price as the original OTA. Manage my booking now correctly shows that I booked what I purchased (economy standard) and that the 1st bag is complimentary both ways.
