No, I agree with others that WN will offer a fare that looks more like a basic JetBlue, Spirit or Frontier fare. The benefits I expect changed around include:

-Boarding order
-Potential Carry-on bag changes (note, I did not say checked bag changes)
-Much stricter change or travel funds flexibility goes away

It doesn't matter where it goes in the order because WGA will be the name of the lowest category of fare with many existing WGA benefits moving away to that new plus option.

All of this is too bad, but Southwest is not a low cost option for many anymore.
