At Pearson you no longer are able to use Biz Class check in. There are now 2 lanes in the regular check in area that are marked Priority. Take your bag there. When you online check in (or at the Airport) when prompted for number of bags there will be no charge for the first one. Excess charges only for second (and more) bag(s). Boarding pass will be coded AC*CC and say Zone 2. when you go to the lounge present your CC with boarding pass for your once a year one time entry. Note: the free bag and lounge access only apply to Aeroplan reward tickets. You don't get these perks when travelling on paid tickets.
