Bonus tier points confirmed.
Total Rewards Site
Two big trips will earn you diamond. I assume diamond in a day is gone, or will be increased to 5,000 tier points.
The math on that page confuses me. The examples don't make sense to me, but that just may be the cabernet.
There are also different levels of diamond. 40k tier gets you a free 4 night stay at any destination. 80k tier gets you a free flight for that free stay. Not sure where the cutoff for free diamond lounge in AC will be.
Chances are this will keep me from making diamond (missed this year anyway), but the daily tier bonuses make the tier level increases seem reasonable to me. As long as I keep getting comped/discounted rooms I will probably stick with CET.
