I was charged $130 to check my baggage from Santiago Chile to New York. It was only one baggage checked and it wasn’t fully the standard size. And then to get hit with $130 was to me not favorable to the airlines. Because on most international travel, they allow one bag to be checked in. So in the future, I would have to think twice about booking Latam again other than that it’s a very good airline.

FAQs about flying to Buenos Aires

Buenos Aires climate

The seasons in Argentina are the reverse of those in the Northern Hemisphere. Summers are humid and can be oppressively hot with January and February temperatures in the 30s (Celsius) and higher. Winters are mild and rainy, and June and July temperatures rarely going below freezing. Spring and autumn are in the 20s.

Getting around Buenos Aires

The oldest subway in South America, the subte, is a quick, cheap and efficient way to get around Buenos Aires. The buses can take you anywhere, but it may not be worth the effort to figure out the routes. Buenos Aires is great to walk around – lovely streets, plazas and parks. You can also grab a radio taxi, which is safer than street taxis. You can identify them by the plastic light boxes on their roofs. Make sure you know your destination’s address and cross street, as some drivers don’t know the city very well. You don’t need a car to get around the city, but if you drive, make sure you find out the rules of the road. 

What is good to know if travelling to Buenos Aires?

  • Wander through one of Buenos Aires’ most important sites: the resting place of Eva Peron at the Recoleta Cemetery. The minute you walk into the grand gates of the cemetery you’ll realise that it’s not like any other you’ve ever visited. Stroll through the passageways where Argentina’s elite are buried, and explore the most ornate tombs you’ll ever see in your life; there’s even one that’s a mini replica of the Sagrada Familia.
  • The heart and soul of tango is Buenos Aires, and whether you stop into a café or a professional dance hall, tango lessons are widely available. But if you’d rather just sit back and watch then head to one of the milongas and experience an authentic tango in motion.
  • If you’re after a little something different to take home with you then you’re in the right place. Weekend markets are a favourite among visitors and the Feria de Mataderos in the Mataderos barrio is the most exceptional one. Another great place to visit is the Librería Alberto Casares where you can spend endless hours rummaging through the bookstore’s impressive collection of antique books and old maps.
  • One of the things you’ll notice is the Argentines’ obsession with football. If there is a game going on while you’re there, book a seat in the platea section and watch the amusing fans sing, jump, and sometimes even fight.
