On the trip I just got back from, on day two it just didn't seem like my points were going up like they should. They were only like 8500. So I went to the window and my tier credits were over 100,000. I had two supervisors look into it on two different days, and both basically blew me off. So figuring out what your points are from what your tier credits are - shouldn't it be as follows: 1 point = 10 tier credits. So 196,000 tier credits earned - divided by 10 would be 19,600 points - then add another 30% for being platinum - and that should add another 5,880 and I should have had 25,480. I ended up with only 15,500. So 155 in point play, and 152 in express comps. Is my calculation correct? Thanks.
