Madrid → Barcelona
A short flight within Spain. No clock change on arrival.
The heart of Spain
Madrid sits high and dry on Spain's central plateau, a wide, grid-and-boulevard capital with no coast and a continental climate of hot summers and cold winters. It is one of Europe's more transit-friendly capitals: an extensive metro plus commuter rail covers the city and reaches the airport directly, and the historic core is easy to walk. Spanish life runs late, with dinner and the evening rhythm starting well after dark by other European standards. A car is rarely useful inside the city center.

The Catalan capital
Barcelona is wedged between the Mediterranean and a ring of hills, a dense grid city built around Gaudi's architecture and a historic Gothic core near the waterfront. The metro is extensive and reaches the airport directly, and most of the city is easy to cross on foot, bike, or rail. It is the capital of Catalonia, a region with its own language and a strong, distinct sense of identity from the rest of Spain. Beaches sit right at the edge of the city grid, unusual for a major European urban center.

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.
