About the Buenos Aires → Sao Paulo route
Buenos Aires to São Paulo is one of South America's busiest air corridors — a roughly two-hour hop across the Río de la Plata basin that punches well above its weight in terms of airline interest. Six carriers operate it, including LATAM (LA) and Aerolíneas Argentinas (AR), which tells you this route serves both the suits-and-laptops crowd and the family-visit contingent in roughly equal measure. At 1,722 km and a flight time of about two hours and two minutes, it's technically short-haul, though the international formalities mean you'll want to budget your day accordingly.
Why travel from Buenos Aires to Sao Paulo?
The obvious answer is business — São Paulo is Brazil's financial capital, and the flow of commercial traffic between Argentina and Brazil never really stops. But plenty of people make this trip for reasons that have nothing to do with spreadsheets. Argentines cross over for the food scene (particularly in Pinheiros and Vila Madalena, where the restaurant density is absurd), for Brazilian carnival if the timing works, and increasingly for music and nightlife that operates on a different register than Buenos Aires. Family connections are huge on this route — there's a substantial Argentine community in greater São Paulo. And for shoppers, the city's malls and electronics prices relative to Argentina make the trip pay for itself faster than you'd expect.

Practical tips for EZE → GRU
Arrive at GRU knowing it's a sprawling airport — Terminal 3 handles most international arrivals and immigration lines can be slow, so clear an extra 45 minutes. The Expresso Aeroporto bus into the city center is reliable and cheap; taxis are fine but confirm metered fare before you get in. The currency is the Brazilian real, Portuguese is the language (Spanish gets you approximately nowhere, despite what optimists claim), and Argentine passport holders don't need a visa. Fly between April and June for lower fares and dry weather in São Paulo. The two cities share a time zone most of the year, so at least jet lag isn't your problem.

Most nationalities require a visa to enter Brazil, though some countries (like the US, Canada, and Australia) can obtain e-visas online, while others must apply at a Brazilian embassy beforehand. Argentine citizens have special MERCOSUR agreements allowing visa-free entry with just their national ID card.
What should I know about luggage, jet lag, and connections on this route?
As a short 2-hour flight, jet lag is minimal since both cities are in the same time zone; luggage policies vary by airline so check your carrier's allowances. If connecting onward from GRU, allow at least 2-3 hours for domestic connections or 3+ hours for international flights, as São Paulo's airport can experience delays.
