Lyft Pink is opt in after the expiration. You do not need to cancel. It gave me the option for 3 more months free if I sign up and pay after. Not happy. I guess that I'll evaluate and choose on a month by month basis. In a normal month, it pays off, but it depends.
This is really the only special benefits I've been getting. None of the airports I frequent have any Priority Pass Lounges, and when I'm at different airports, I'm generally going to be on international business class tickets so I get lounge access anyway.
