Argentina is a long-haul destination from everywhere except neighbouring South America. Most international visitors arrive at Buenos Aires Ezeiza (EZE), which is 45 minutes from the city centre - not a quick transfer. The country has two major airports serving Buenos Aires with completely different roles: EZE handles long-haul international flights, while Aeroparque (AEP) handles domestic and regional services including routes to Santiago and Sao Paulo. Understanding which airport you are using matters more here than in most countries.
The currency situation is genuinely confusing. The Argentine peso is volatile, and the “blue dollar” parallel exchange rate means your money goes significantly further if you plan ahead. Carry US dollars. The practicalities of paying for things in Argentina require more thought than you might expect, but they are manageable once you understand the system.
I visited Buenos Aires, explored multiple neighbourhoods extensively, flew in and out of both airports, and continued onward to Santiago. The food and culture are exceptional. The logistics require a bit of homework. Here is what you need to know.
