CHEAP! Full-service flights from Porto to Buenos Aires, ARGENTINA for €494 with Ethiopian Airlines & TAP!

Travel period

January – February 2027

Cheap full-service Porto to Buenos Aires from €494 on Ethiopian Airlines & TAP with 2 × 23 kg check-in baggage included — proper long-haul handling with meals and 46 kg of hold luggage on a Star Alliance routing at a fare that would be hard to match even on stripped low-cost bases to South America. Buenos Aires is Argentina's soulful capital: European boulevards in Recoleta, colour and tango in La Boca, late-night steak and Malbec in Palermo, and café culture that runs until the small hours — gateway to Patagonia, Mendoza wine country, and Iguazú when you want more than the city.

Dino found sale dates in January and February 2027 — peak southern-summer warmth in Argentina, long daylight evenings, and outdoor terrace season when Europe is deep in winter. Routing runs through São Paulo Guarulhos (GRU) on the Ethiopian and TAP combination: full-service carriers, checked bags baked in, and a price that makes a long South America trip from northern Portugal genuinely affordable if you can stomach the schedule.

The catch — Dino will be straight with you: both directions involve a very long connection in GRU — almost a full day on the ground each way. That is not a slick two-hour hub turn; it is an airport marathon that will suit patient travellers, anyone happy to book an airport hotel, or those who can legally leave the terminal for a taste of São Paulo between flights. Many people would rule this out immediately — and fairly. But at €494 return with 2 × 23 kg included, it is a compromise some bargain-hunters will accept for full-service flights to Argentina from Porto. Confirm exact OPO/GRU/EZE flights, GRU wait times both ways, whether bags are checked through, Star Alliance benefits, fare rules, and Argentina entry requirements for your passport before you pay.

Dino Verdict

A cheap Argentina fare with great baggage, but very long layovers

This is a very interesting fare because it combines a low price from €494 return, official airline booking, and 2 × 23 kg checked baggage included. For Porto to Buenos Aires, that is excellent value.

The big downside is the journey time. The sample itinerary has around 33h05 outbound and around 35h50 on the return, mainly because of very long layovers in São Paulo Guarulhos.

Dino sees this as a cheap-but-slow Argentina deal. The price and baggage are excellent, but the layovers are not a small inconvenience — they are basically part of the trip.

Price 9.4/10

€494 return from Porto to Buenos Aires is excellent, especially for a direct airline booking.

Baggage 9.5/10

2 × 23 kg checked baggage included is a huge advantage at this price level.

Booking reliability 8.5/10

Booking directly with Ethiopian Airlines is a strong positive compared with relying on an OTA.

Routing 6.8/10

One stop via São Paulo is logical for South America, but the total journey time is very long.

Layovers 4.5/10

Around 19h20 outbound and around 23h05 on the return in GRU is the biggest weakness of this fare.

Availability 8.8/10

Several dates were found at the same price level, which makes this more useful than a one-date-only fare.

Why this deal stands out

€494 return to Buenos Aires with 2 × 23 kg checked baggage included and direct booking on Ethiopian Airlines is very strong value.

What to check before booking

Check whether you are comfortable with the very long São Paulo layovers, confirm the final baggage allowance, Brazil transit rules, Argentina entry requirements, cancellation conditions and final payment total before booking.

Best for: budget travellers, backpackers and flexible travellers who want the cheapest possible Argentina fare with baggage included.

Less ideal for: families, short trips, comfort-focused travellers or anyone who dislikes very long airport waits.

Where to stay in Buenos Aires

With our sample flight, you arrive in Buenos Aires on 19 January. We recommend spending at least 3 nights in Buenos Aires before heading off for a broader trip around Argentina.

Buenos Aires is a great city to start your Argentina adventure: elegant neighbourhoods, steak restaurants, tango culture, historic cafés, colourful streets, football atmosphere and plenty of affordable hotel options compared with many major European cities.

For a sample hotel search from 19/01 to 22/01, we found many well-rated 4-star hotels from only around €90 per night. When travelling as a couple, that works out at approximately €45 per person per night, making Buenos Aires a very affordable base for the first few days of your trip.
