    Use the likes of Skyscanner to check, prices vary notably and its rare that one airline is always cheaper but will vary by airports, dates etc.

    Skyscanner is a great tool for comparison.  Be careful though if you click through to book as they often link to the cheapest website/OTA that may not have the best customer service.  Try and book direct with the airline if possible.

    Another excellent site is Search flights || ITA Matrix by Google ( which is the brains behind Google Flights.  Allows many combinations of dates durations and even nearby airports.

    For both cases you will need a "multi city" search.

    I've just done exactly this for Mrs Wonka (albeit for Sept '23).

    A lot depends on starting point in UK and your view of price vs complexity. She ended up with the one BA direct flight from LHR-SCL then GRU-LHR - both of these knocked about 5hrs off the journey time and were only about £75 more than the cheapest indirect option.

    The two airlines with the widest choice of flights are Iberia and TAP Air Portugal but flight prices all depend on supply, which they clearly have a lot and demand which will vary from day to day and month to month. There is no simple answer to the question, as others have suggested look to the likes of Skyscanner for what is available but do not book with 90% of the agents on there as you will live to regret it. If you have never heard of the company, avoid it like the plague

    I always found Air France/KLM offered decent prices to and from South America but just go onto and find the best deal for your specific route.

    You might find the best price is a return ticket to brazil and then internal flights to connect you to where you want to go. 

    Norwegian used to do great one-way tickets to and from Rio for £199 but no more, sadly.
