I'll be traveling to Argentina in the next few weeks and are looking at booking flights from BA to el calafate through LAN's website. My plan was to book the tickets through the Argentinian site rather than the international site as the flights are much cheaper. The only thing is that when I go to book the tickets, there is a notification saying that these tickets are for Argentinian residents and that documentation will be checked on boarding.
I know other people (non residents) who have done this in the past and had no problems but am wondering if things have changed. Does anyone know?
