Gotcha. The US trial is a definite possibility since when the programs are merged it should carry over. The big drawback is that you'd have to maintain it long enough for the programs to be merged. That means flying US/USX metal enough to meet the qualification of the level you want within 90 days, then flying enough annually on *A carriers to maintain that status. If you meet the trial there a cutover date which I don't know - before that the status is good until the end of February of the next year, after it good till the 2nd February following qualification. Maybe someone else can post whether qualifying now would give status till 2/28/2014 of 2/28/2015. Chances are that the programs won't be merged by the end of February next year since US will likely still be in the *A. So you'd either need the trial status qualification to last to February 2015 or retain status by flying.
