Although I was in economy it made no difference where the staff were concerned they were attentive and pleasant throughout the flight maybe one day I'll get the chance to see if there's a difference in business or 1st class service but in truth for the way I was treated I can only see the menu being an upgrade as the staff don't need upgrading and are indeed the biggest asset on a long journey a credit to the company.

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.

Getting from the Airport to the City

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.

Weekend markets are a favourite among visitors and the Feria de Mataderos in the Mataderos barrio is the most exceptional one.
