Route notes
Why this routing works
This routing uses Reykjavik as the first transatlantic stop, then continues to Stockholm before a surface sector to Helsinki. The open-jaw between Stockholm and Helsinki avoids doubling back and lets the final long-haul return depart from a different Nordic gateway.
Across four weeks, the timing leaves room for a longer stay in Reykjavik at the front of the trip, followed by the Sweden-Finland segment later on. In ticketing terms, it is a straightforward multi-stop structure with one overland gap built into the sequence rather than replacing it with an extra intra-Nordic flight.
In economy, the trip is paced around two transatlantic crossings with the Nordic portion split between flown and surface travel. September departure timing fits a late-summer routing pattern, with the overland Stockholm-Helsinki segment acting as the key break in the air itinerary.
