Per this FlyerTalk thread, American has published a ~$900 all-in business class fare between New York and Santiago, Chile, valid for travel on American and LAN (though only on LAN in conjunction with an American Airlines codeshare). I’m not sure if this is a legitimate fare sale (given that we’ve seen several fare sales to South America in the past week) or a fat finger mistake, but I’d definitely get in on this as soon as possible. It seems to be valid for travel through early June.
The best place to look up availability is on ITA Matrix. Enter the origin and destination, your date flexibility, and select business class, and it will return options in a calendar view.
Then just select your preferred dates/flights, and you should be able to book them on aa.com. While there’s lots of routing flexibility with this, all flights need to either be on American or be an American codeshare. This means you can fly LAN in many cases, and I’d highly recommend booking them in business class between Miami and Santiago over American, as LAN has fully flat seats in business class while American doesn’t. Unfortunately I haven’t found a way to route this through Buenos Aires or Sao Paulo on American in order to get on a three cabin plane (and use a systemwide upgrade to further upgrade to first class), as American doesn’t codeshare between those gateways and Santiago.
C’mon folks, let’s book this!
