Nice post. I guess I've seen all that information in pieces, but never all laid out together. As a UA 1K that's kind of fed up with UA, it's interesting how much AA seems to "win" on upgrades (both domestic and international) at the 100K level.

Can anyone offer some insight on a counter? I.e., why hasn't United matched the AA policy, or why haven't more UA 1K's who like sitting up front gone over to AA?
