LIM tickets have plummeted in cost generally ever since jetBlue began service there (albeit only out of FLL). Ditto Colombia and UIO. As for the flights, I still remember the days when CO offered free elite upgrades to any destination in the northern part of South America, including Lima! (To be fair, I don't think they flew more than a handful of routes there, and I'm pretty sure GRU and GIG weren't included.)
