About flights to Buenos Aires
Overview
Buenos Aires, Argentina's captivating capital, is a city of grand European boulevards, passionate tango and superb steak — often called the Paris of South America. Its elegant neighbourhoods, buzzing café culture and rich arts scene make it a highlight of any South American trip for UK travellers. Long-haul flights arrive at Ministro Pistarini International Airport (EZE), commonly known as Ezeiza. Comparing fares in one place makes finding the right flight to Buenos Aires quick and simple.
Best time to fly to Buenos Aires
Buenos Aires lies in the Southern Hemisphere, so its seasons are reversed. The most comfortable periods are spring (September to November) and autumn (March to May), with mild, pleasant weather. Summer (December to February) is hot and humid, while winter (June to August) is cool but rarely cold. Fares generally ease outside the festive and peak summer weeks, so travelling in the shoulder seasons stretches your budget further — check the price charts on this page for your dates.
Airlines and routes
There are no direct flights from the UK to Buenos Aires, so journeys connect via a hub. Popular one-stop options include British Airways and Iberia (via Madrid), Air France (via Paris), KLM (via Amsterdam), TAP Air Portugal (via Lisbon) and Lufthansa (via Frankfurt). Expect a total journey of around 15–18 hours from London or Manchester depending on your connection. Comparing carriers for your exact dates is the surest way to secure the lowest fare.
Things to do in Buenos Aires
Buenos Aires rewards curious travellers with culture, colour and character:
- La Boca & Caminito: a photogenic street museum of brightly painted houses and tango.
- Recoleta Cemetery: an atmospheric city of mausoleums, including Eva Perón's tomb.
- Plaza de Mayo & Casa Rosada: the historic heart of Argentine political life.
- San Telmo: a bohemian quarter famed for antiques, markets and Sunday tango.
- Teatro Colón: one of the world's finest opera houses, dazzling inside and out.
At Ministro Pistarini International Airport (EZE)
Ezeiza handles nearly all international flights and sits about 30 km south-west of the city centre. Facilities include duty-free shopping, currency exchange, ATMs, lounges and dining. Official airport taxis and pre-booked private transfers are the recommended way into the city; agree the fare or use the official desk before setting off.
Top tips for finding cheap flights to Buenos Aires
- Book roughly 2–5 months ahead — long-haul fares to Argentina rise close to departure.
- Avoid the festive and peak summer weeks; the shoulder seasons are noticeably cheaper.
- Be flexible with dates — midweek departures often beat weekend prices.
- Compare European hubs; each can be cheaper depending on your dates.
Travel essentials
- UK passport holders do not need a visa for tourist stays in Argentina of up to 90 days.
- Carry some US dollars as backup, as they are widely exchanged and useful.
- The local currency is the Argentine peso (ARS); check current exchange guidance before you travel.
Baggage & hand-luggage allowance for flights to Buenos Aires

| Fare type | Hand baggage | Checked baggage |

Packing & baggage tips
- Full-service carriers (e.g. British Airways, Turkish Airlines, KLM) usually include a checked bag on long-haul economy fares; basic/low-cost fares often don't.
- Cabin (hand) bag size is commonly around 56 × 45 × 25 cm — confirm your airline's limit before you pack.
- Liquids in hand luggage must be in containers of 100 ml or less, inside one clear resealable bag.

- Extra or heavier bags are almost always cheaper added online in advance than at the airport.
