Return flights from London to South America typically cost between £925 and £1164 in August, though fares move with demand, season and how early you book. The lowest fare our search found recently was £763 — a great price and well below the usual range, so a price near this is worth grabbing. Keeping your dates flexible and comparing nearby days is the easiest way to land at the cheaper end.
On average, May is the cheapest month to fly to South America, with return fares around £886, and November is another good-value option at about £921. Prices peak in August, when return tickets average around £1336 because of higher demand. If your travel dates are flexible, shifting your trip into a cheaper month can save you a meaningful amount.
The cheapest day to depart to South America is usually Sunday, when fares start from around £975 — midweek departures tend to be quieter and cheaper. Friday is typically the most expensive day to fly out (around £1120), as weekend travel is popular with leisure and business travellers alike. Where your plans allow, moving your outbound to a cheaper weekday can noticeably lower the total fare.
Flights to South America are generally cheapest departing in the evening, with fares from around £877. Departures in midday tend to cost more (about £1057), as those slots are more convenient and in higher demand. Picking an off-peak departure time is a simple way to trim the price without changing your dates.
The cheapest return flights to South America depart from London Heathrow (LHR), from around £760. London has several airports serving this route and fares can vary between them — Stansted (STN) is often the priciest at around £1334. It's worth checking which London airport is both cheapest and most convenient for you before booking.
For South America, prices are generally cheapest when you fly direct, with fares from around £825 versus about £878 for a 1-stop itinerary. A direct flight also saves you time and the hassle of a connection, so it's usually the better all-round choice on this route. Stopovers only tend to pay off here if a particular date or airline happens to be cheaper.
To get a below-average price to South America, aim to book roughly 26 weeks before departure, when fares tend to dip to around £986. Leaving it to the final week is usually the most expensive time to buy, costing about 29% more, as availability tightens. Booking extremely far ahead isn't always cheaper either, so a few weeks to a couple of months out is typically the sweet spot.

South America is a continent of dramatic contrasts — the Andes and the Amazon, vibrant cities and golden beaches, ancient ruins and world-famous festivals. For UK travellers it's a bucket-list region for culture, nature and adventure, reached via direct or one-stop flights to its major gateways.
Seasons are reversed from the UK. The dry season (roughly May to September) suits the Andes and much of the continent, while December to February is warm and lively in the south. Fares rise around Carnival and the festive season — the price charts on this page show the cheapest dates.
British Airways and LATAM fly direct from London to São Paulo and Buenos Aires; connecting options include TAP Air Portugal (via Lisbon), Iberia (via Madrid), Air France (via Paris) and Avianca, serving UK airports including Manchester.
Your allowance to South America depends on the airline and the fare you book. The table below shows typical long-haul allowances so you know roughly what to expect — always confirm the exact limits with your airline before you fly.
| Fare type | Hand baggage | Checked baggage |
|---|---|---|
| Basic / Light economy | 1 small under-seat bag | Usually none — add for a fee |
| Standard economy | 1 cabin bag + 1 personal item | Typically 1 × 23 kg |
| Premium economy | 1–2 cabin bags + personal item | Typically 2 × 23 kg |
| Business / First | 2 cabin bags + personal item | Typically 2 × 32 kg |
