One devaluation was last year was when LH stopped accepting SWU's from Z to F upgrades. Fair enough you may say since UA doesn't allow them either, but still that was a huge draw for me, since India to FRA would usually clear to F and that would provide FCL access in FRA.
This makes it even harder to use.
Then why am I not so upset? Because I have already moved ~65% of my travel to AA/BA/Oneworld after the EXP match, and the decision is looking better every day.
Will still make 0P/1K this year, but effectively, I'm now a Kayaker (at least between *A and OW) and only pick UA when the route/price makes sense.
