I would like to fly up to Iguazu Falls, Argentine side only, after arriving in Buenos Aries after a Cape Horn cruise in Feb. 2018. When I look at booking air fare the best price I see for AEP-IGR-AEP is $357 each on despegar.com picking random dates in Dec. 2017. As there would be two of us, by the time we also pay for a hotel for 2 nights, pay for 2 days of park admissions and meals I'm close to $1000 to see the falls. I don't know if it is worth it.
I cannot find a tour company to sell a package that includes the flights at the "locals" rate. I know the Argentine airlines impose a gringo tax on domestic plane tickets purchased by foreigners.
Any suggestions how to get the airfare down to a reasonable level?
