Still not clear why one LAN direction is treated so differently from the other
It's all decided somewhere in the room of a million monkeys at a million typewriters that passes for airlines' reservation systems. Sometimes when traveling to South America, flying the short LAN legs on AA codeshares costs hundreds of dollars more (and involves substantially worse connections) than with LAN flight numbers. Other times it's the opposite. Often I end up with the outbound as an AA codeshare and the return as a LAN flight. There may be some internal rhyme or reason to it, but on my end it seems random.
