Cheap Flights from Porto Alegre to Buenos Aires

December to February are the expensive stretch, with southern summer, Christmas and New Year travel pushing demand in both countries. March can still be busy, while the cheapest month named in the data is June, with May and July close behind; late June also sits outside school holidays for many travellers. Midweek departures usually price lower than weekend ones, and September has no fare data in this calendar, so check nearby months if you are flexible.

The difference you feel is between low-cost and full-service tickets: Azul and GOL Linhas Aereas S.A. usually sell lower base fares with bags, seats and meals charged separately, while LATAM Airlines, Latam Airlines Brasil and Aerolineas Argentinas more often bundle a checked bag and onboard service. Direct flights run on this route, though whether your chosen airline flies nonstop or connects depends on the date and fare. Both LATAM names can appear in results, so read the operating carrier line before you pay.

Arriving late in the day changes the transfer: public transport thins out and a taxi or ride-hail becomes the practical option, so check your landing airport before you book. Jorge Newbery sits close to the city, while Pistarini is farther out, and the two are not interchangeable for a late arrival. If you land at Pistarini after dark, allow extra road time into central Buenos Aires.
