We would love to fly LAN in business class to South America----into SCL and out from EZE. I know I have to call AS for LAN bookings, but is it even possible to book two seats in the premium cabin?

I have been "practicing" for a potential upcoming booking, and can view LAN award seat availability on BA.com through my BAEC account. Looking 330 -334 days out (as soon as the seats are released), I have seen only ONE seat in business class on each flight. I checked to and from LAX and MIA, to and from SCL and EZE. Never two, only one.

When I tried this exercise several months ago! there seemed to be multiple seats available. Has something changed? Has anyone been able to score two seats in business class on these routes recently?
