Stockholm → Helsinki
A short flight from Sweden to Finland. Helsinki is 1 hour ahead. Remember to put your watch forward when you land.
The city built on fourteen islands
Stockholm is spread across fourteen islands where Lake Malaren meets the Baltic Sea, a city defined by water, bridges, and a well-preserved medieval old town, Gamla Stan. The Arlanda Express runs nonstop from the airport into Central Station in 18 minutes, one of Europe's quicker dedicated airport rail links. Summers bring long daylight, with nearly white nights in June, while winters are dark and cold with limited daylight by December. The city's metro, ferries, and extensive bike network make a car largely unnecessary within the urban core.

The Nordic gateway
Helsinki sits on a peninsula and archipelago at the edge of the Baltic, a small, clean, and orderly Nordic capital with a compact, walkable center. A direct rail line connects the airport to downtown in around thirty minutes, and trams and a small metro cover the rest of the city well. Winters are long, dark, and cold, with snow on the ground for months, while summers bring very long daylight hours in compensation. It sits far closer to Russia and the Baltic states than most Western European capitals, both geographically and historically.

Notes from the product.
Small updates, route observations, and clearer explanations for how the app keeps evolving.
Type less, wait less, wonder more

Airport search now understands metro codes and old city names, FlightSide loads noticeably faster, and a new Feeling lucky button chooses a flight for anyone without one in mind.
A closer look at the route, not just the seat
FlightSide now shows the two cities and key details about the flight alongside the seat recommendation: confirm you picked the right airports, read the time change off two clocks, and check the return leg.
It's all about the sun (after all)
Not all sunlight reaches the side windows. FlightSide now weighs the sun’s angle to the cabin and shows twilight along the route.
