I think they're expecting pent-up demand and needing to send people away so limiting as a Membership Extra effectively is a first filter. I can see it rolled back eventually to again include white cards. Then again, it could do better business being more exclusive. Both blue and white card members feel the sense of "club" and the more limited something is the more "special" it feels for more people. People that feel more special are more willing to spend more money. Club 33 and Golden are the extreme examples of this. Maybe limiting gets more blue cards up to want to go up there and pushes a few more drink sales, but it will absolutely have some impact on direct sales. Pushing a blue card lounge is a useful differentiator especially when APs are not being sold.
