This is a pretty steep price increase if you were using the MVPG or MVPG 75k discount to get the current membership. To keep the same benefits (via Alaska Lounge Plus) you'll pay $150 (MVPG) or $200 (MVPG 75k) more.
Now that the Alaska Lounges are open again to Priority Pass memberships I'm not sure at all what the value is here, other than guaranteed entry which at current travel volume seems unnecessary?
