The rolling EQD requirement makes me rethink my qualifying strategy. My CPM is right at the level where I will pass the EQD threshold barely before I pass the EQM threshold. What I've done in the past is spread out my travel between AA and UA, qualifying for EXP and 1K. My travel patterns allow me to purchase 4-6 weeks before travel, which puts me pretty high on the upgrade list for my domestic travel. With an EQD level of ~$12K I will now be Tail-End Charlie.
So, I have a choice. Take my $12K from UA and apply to AA, or take my my $12K from AA and apply it to UA. Fish or cut bait, which I'm sure is EXACTLY what AA is trying to incent me to do. Unfortunately, my travel patterns don't make it easy to give up one or the other.
