Using the points calculator, the highest I can achieve will only be silver. If I travel in J, Silver won't give me additional benefits.

And if I'm not travelling in J and I'm with my wife, who travels a lot less than me, she won't have lounge access. So we'll end up using the Plaza Premium lounges.

I guess I won't join MPC. I haven't traveled alone, always with friends and family. So even if I have status, and my companions don't, I won't be able to fully enjoy the benefits of MPC.
