Depends on alot of things... for example, you could be the only Platinum on the flight and all the rest of the elites are Silver. You would trump them when EUA runs, but not know that from the fares that have been previously sold. I usually look at loads a few weeks in advance and see what flights fill up and which ones stay in the F9 category on ITN the longest. I'm on several flights this weekend where I'm the only one up front.
