Cheap Flights from Dublin to Rio de Janeiro

Rio runs its seasons upside down: December to February are the hot, long-daylight months, when Christmas, New Year and Carnival keep demand high, while June to August bring cooler, drier air and a calmer city.

Fares follow that curve. November is the cheapest month on the board — after the southern winter, before the summer rush — and the price calendar here runs from September to June, skips July entirely, then picks up again in August. Midweek departures usually undercut weekends.

Almost the whole field here is full-service: Lufthansa, Swiss, Air France, Iberia, Turkish Airlines, United Airlines and LATAM sell connecting itineraries on a single ticket. Air Transat is the leisure-style alternative, Portug adds a further European connection, and HOP! appears as the regional leg feeding Air France from Paris.

What a fare includes matters more than the logo: network tickets typically bundle a checked bag and meals on the long leg, while the leisure option often sells bags separately, so price the total with luggage added. Routings differ as well — Turkish Airlines swings through Istanbul, United crosses the Atlantic first — which changes your journey time.

Plenty of connecting schedules put you down in Rio late in the day, which shapes your first hour: Rio de Janeiro International sits far out on the north side of the bay, so the drive to the centre or the southern beaches takes real time after such a journey.

Santos Dumon, the city's second airport, sits right beside the centre and takes most domestic traffic. App-based cars and regular buses serve both fields — order your car before you step outside, and see which of the two airports your booking uses, because mixing them up turns a short transfer into a long one.

Country facts: Wikidata

• Book both legs on a single ticket, because two separate bookings leave you without protection if the connection fails.
• Leave a generous gap at your connecting airport; a tight transfer is the common way to lose the long-haul leg.
• Check whether baggage is included before you commit, as the leisure carrier often sells bags separately.
• See which Rio airport your booking uses — Rio de Janeiro International or Santos Dumon — and plan the transfer to match.
• Check the entry rules Brazil applies to your passport, including any visa or onward-ticket requirement.
• Aim for November when your dates are flexible, since fares dip there ahead of the southern summer.
