AC will continue to take the worst from other FP programs.
For example, I'm still shocked that Alaska and United don't offer universal system-wide lounge access regardless of fare class, as long as you have *G (or equivalent).
So I expect that AC will no longer offer Lounge Access, especially since their lounges are 10x better than United/Alaska. Maybe SEs will get a "discount" or 4 free entries.
Then there's LH, which only gives 25% bonus to Senator and even HON members. So SEs will now only get a 25% bonus, not 100%.
Oh and if we're comparing it to LH, AC will consider SE to be like HON, so they'll require 600K miles in two years. 50% on AC metal.
