Cheap flights from Dublin to Oslo

December is the cheapest month on the calendar for this route, when cold and short days keep demand down. Prices climb through spring and sit high across the summer, with July the month Norwegians take their own holidays.

Midweek departures tend to price below Friday and Sunday flights on short European hops. Around Christmas, Easter and the school breaks, seats go early, so book ahead if your dates are fixed and stay flexible if you want the winter lows.

What a fare includes is where these airlines differ. Norwegian, with Norwegian International under the same banner, sells near-bare tickets: a small under-seat bag is standard, while a cabin bag, seat selection and checked luggage cost extra. Aer Lingus and SAS sit in between, folding a cabin bag into most fares and pricing checked bags by tier.

British Airways, Air France, KLM and Lufthansa connect through London, Paris, Amsterdam and Frankfurt, and their standard tickets include a proper cabin bag, with checked allowance tied to the fare type. Widerøe completes the list, a Norwegian regional carrier that appears in some connecting itineraries.

You will usually land at Oslo Airport, the main gateway, which sits a good stretch north of the city centre. Express and regional trains run into town, with coaches as the slower, cheaper alternative.

A share of itineraries use Sandefjord instead, a smaller field on the coast well to the southwest, where a coach into Oslo makes the door-to-door day longer. Look at the airport code before you pay, because a lower fare can shrink once the transfer is added.

Country facts: Wikidata

• If two airlines are on separate tickets, leave slack between the flights — the second carrier won't rebook you if the first runs late.
• Weigh what each fare includes: with Norwegian and Transavia France, bags beyond a small under-seat case cost extra.
• Check which Oslo airport your booking names, Oslo Airport or Sandefjord, because the trip into town differs sharply.
• Norway is in Schengen, so confirm the passport and visa rules for your nationality before you pay.
• Fares bottom out in December and climb into summer, so it is worth pricing flexible dates across both seasons.
• Direct flights from Dublin skip the connection risk, which counts for more in winter when delays stack up.
