Folks - I have to leave from Porto Alegre, Brazil, for a 4-day stay in Brisbane, Australia, in August 2013 (a scientific conference). I've been reading about companies, and Aerolineas Argentinas is the cheapest AND the most troublesome. What to say about LAN, which flies through Santiago? Emirates, with stops into Dubai:
AND - should I try to fly eastbound or westbound, regarding jet lag?
