Effective January 1, 2019, Delta Sky Club members may only use the Club in conjunction with same-day ticketed air travel on Delta or its partner airlines and will no longer have access to partner lounges.
This change will result in annual 6 visits in 2019 vs my current annual 120 visits. This makes my lifetime investment to nothing.
I may need to study the term for possible class action...
