First, a sad news that the Platinum spend became from 8k to 12k with no higher bonus. Now you can redeem Air Canada points on ITA like United.
Good news for Platinum cardholders is that if you are flying any airline in Lufthansa Group, you can get Lufthansa lounge access, unlike before when it was Lufthansa, Austrian, and Swiss. That is all, but later I may add a comment thread later.
