And again, Delta's super-incredibly-amazingly-awesome-critically-important lead among international seats out of LAX is not nearly as important as certain dead-horse-beaters continually repeat because AA is no slouch in terms of international network breadth and depth out of LAX. Congratulations to Delta for being larger out of LAX to international markets - for now - but the context is important, given that it's largely driven by VFR- and/or leisure-heavy markets in Mexico and Central America, and given the fact that AA offers nonstop access to notable premium/business international markets where Delta is absent (GRU, YYZ, etc.).
As already said - I don't think AA is too worried, what with their extensive domestic and international network out of LAX, 3-class transcons, enviable gate position (including, soon, heavy TBIT access), etc.
Reality.
