As to LAX-ICN, it's the polar opposite of a long-and-thin route that cries out for the tiny 787-8. Between KE and OZ, there are multiple daily A380s, along with some 77Ws and 77Ls thrown in. LAX-ICN is the largest market between the 48-states and Seoul, and if DFW warrants a potential upgauge to a 77W, then filling a 777 from LAX should be simple.
MIA-EZE is the largest market between the USA and Argentina, and AA carries about three times as many passengers on that route as it does on DFW-EZE (a route I would describe as "thin"). AA dominates traffic to South America, and its Latin America yields (average fares) are far higher than Delta or United in Latin America. Against all that, I don't see MIA-EZE warranting a smaller plane unless it's a daily third flight (an addition) from MIA.
Ah, you are forgetting what has happened in Argentina (similar to Venezuela) and how it has affected the MIA-EZE route. It's not been doing well for the past couple of years, although it is still profitable at least for now. So in my head it makes more sense to fly the 787 on routes where you can maximize profits rather than fly it on thinner routes where you can make some profit. But again, guess AA knows best!
