$835 - Flights to Buenos Aires Argentina from San Francisco
LAN Airlines is offering one and two stop flights to Buenos Aires from San Francisco for $835 including all taxes and fees.
Their website offers flights for $799, but the cheapest flights I’ve found cost $835.
As an alternative, you can fly to Argentina with Continental Airlines or American Airlines for just over $1000 if you book ahead of time.
LAN Airlines requires that you stay for more than 4 days, including a Saturday, which shouldn’t be too hard to do after taking 20 hours to get there..
From Buenos Aires, a lot of travelers head straight to Mendoza as well, Argentina’s wine region which is a little over a 10 hour bus ride from Buenos Aires.
