Air Canada's upgrade bidding method offers an ideal option to secure a better seat without paying the full price. Using their "Bid Up" program, you can place a bid for an upgrade to business class or premium economy after booking your flight. Air Canada Upgrade is about offering a price you're satisfied with, which will then be considered against other bids based on factors like seat availability, demand, and your loyalty status. After you submit your bid, the airline will consider it, and if your offer is successful, you’ll receive a confirmation mail for your upgraded seat. While bidding doesn’t guarantee an upgrade, it’s definitely worth trying, especially if you're flexible with your offer.
