Another thought...merging AA and LCC will not create a competitor to Emirates. Keep in mind that Emirates is a state-owned and state-financed airline. And the state (Dubai) is awash in billions of oil dollars. No one, including BA, LH, DL, UA, or the "new" AA can compete with that kind of financing.

Exactly my point, although like a moth to a flame, 700UW feels compelled to argue the superiority of the US international network whenever someone brings it up.
It's delusional to believe that AA can't compete with Emirates unless AA is combined with the US European network, which consists of two flights to London, a few flights to Germany, Ireland and France, and about a dozen miscellaneous mostly seasonal second-tier cities like Lisbon and Venice. If that's all it takes for AA to succeed, then AA needs to duplicate that huge US European network, none of which are restricted destinations (in other words, they're all open skies destinations to which any airline could fly).
It's similarly delusional to believe that US+AA can successfully compete with Emirates over the long term. When EK is eventually flying more widebodies than UA, DL, AA and US combined, it will probably win.
