Booking Strategy
For Dublin to Reykjavik, book 3-6 weeks ahead for summer travel (June-August) and 4-8 weeks for winter. Play typically launches their cheapest seats 6-9 months before departure, so setting alerts for this route pays off. Tuesday and Wednesday departures are consistently €40-80 cheaper than Friday-Sunday. Use Skyscanner’s ‘whole month’ view to identify cheapest dates — early February and late October often show €250-280 return. Avoid school holidays (Irish midterms, Christmas) when prices spike. If flying with Icelandair, their ‘Stopover’ option lets you explore Iceland briefly at no extra airfare cost — ideal if you have time. Book directly with airlines rather than OTAs to avoid booking fees and get better customer service for changes.
Route Tips
- Keflavik Airport is compact and efficient — allow 90 minutes for international departures as security can get busy. There are minimal shops or restaurants airside, so bring snacks.
- Irish and EU citizens need only a passport or national ID card — no visa required. Non-EU citizens need 3 months valid passport beyond arrival date.
- Use the Airport Direct Flybus — book online in advance at re.is for €25 vs €30 at the door. The bus has free WiFi and power outlets.
- Icelandic weather is unpredictable — even in summer, bring layers and waterproofs. The ’10-minute weather’ saying is real — it changes constantly.
- For northern lights, download the Veður app — it shows aurora forecasts hourly. Drive 20-30 minutes north of Reykjavik to escape light pollution for the best views.
- Skip the expensive restaurant lunches — grab hot dogs (pylsur) at Bæjarins Beztu for €4-5, considered one of the world’s best street foods.
- If renting a car, book through local company Lotus Car Rental rather than international chains — significantly cheaper and excellent service. Book well in advance for summer.
