Frequently asked questions

Can I cancel my flight booking to South America due to COVID-19?
If you haven't booked yet, look through the terms and conditions of the airline you're considering. If you've already reserved your flight to South America, visit our Customer Service Portal. The information here will help determine which COVID-19 policies are applicable to your reservation and advise the next steps.
What's the best way to find cheap flights to South America that have flexible change policies?
When it comes to flying these days, flexibility is important. That's why we have a "No change fee" search function to help you track down flexible and cheap tickets to South America. It's on the left of your screen underneath the "Flexible change policies" subheading.
What are some of the general tips for travelers to South America during the COVID-19 outbreak?
The COVID-19 pandemic has changed how we travel, but it hasn't shut down our desire to explore. Here are some tips on how to cope with travel's new challenges:

  • Find out the rules and restrictions in both your destination and origin. It may not be possible to travel depending on local circumstances, so check before you lock something in.
  • You're required to wear a face mask at the airport, including at security checkpoints. Be ready to lower your mask for ID purposes when asked by a TSA employee.
  • Rather than handing a TSA officer your boarding pass, position it straight on the scanner yourself. After that, hold it up for inspection.
  • One liquid hand sanitizer container is now permitted in your carry-on baggage. It must be no bigger than 12 oz (350 ml), and you'll need to take it out of your bag for X-ray scanning.
  • Place any personal items (phone, wallet and keys) in your carry-on rather than a bin to reduce handling during the screening process.
  • If you're taking food on the plane with you, place it in a clear plastic bag and then into a scanning bin. This lessens the likelihood that a TSA employee will need to touch your carry-on bag or food container for inspection.

  • Kick off your South America vacation in the lively city of Sao Paulo. There's loads to keep you amused here, from top attractions like Paulista Museum to wonderful food, shopping, arts and more.
  • Sao Paulo is known for its humid subtropical climate. But before you jet off, check out what the weather will be doing while you're there. Hot, cold, wet or dry, it's always wise to arrive prepared.
  • Be sure to make Campinas the next place you go to. It's 80 kilometres to the northwest of Sao Paulo and where you'll find Museum of History and Porcelain of Pedreira, one of this destination's best tourist sights.
