I love #s 2, 4, and 6. Also I like the reward chart, much easier to read that then having to click through all the series on the website in my opinion.
I am curious as to #7, the change from 2 points to 1.5. Earlier in the year I had only 45k EQM with 90ish points until my international travel kicked in, but it was nice making platinum by buying full fare tickets to short destinations on ERJs. One of the biggest benefits of status is EUA but that option isn't even available if you are on an ERJ. If you are on flights often with first class cabins then you are already gaining plenty of EQM and the points don't even matter much. I just don't see the reasoning as to lowering it to 1.5 points when it really only hurts the regional hoppers who receive almost no benefits already if all they fly are ERJs.
If the threshold remains at 90 points, I would see myself buying fewer full fare tickets on regional jets since the main advantage for me would be gone. It would now take 60 full fare flights versus the previous 45. Overall though, I really like the changes.
