Frankfurt → Vienna
A short flight from Germany to Austria. Your watch stays put on arrival.
Germany's financial gateway
Frankfurt is a small city with an outsized role: Germany's banking capital and one of its busiest hubs, with a rare real skyline for Europe. The compact center sits on the river Main and is easy to cross on foot or by an efficient rail and U-Bahn network. It is a business city first, quieter on weekends, and tied to the rest of the country by fast trains. Its airport is one of Europe's largest interchange points.

The city of music
Vienna is a grand, orderly former imperial capital ringed by the Ringstrasse boulevard, with palaces and a deep classical-music history at its center. The U-Bahn, trams, and S-Bahn cover the city comprehensively, among the more transit-complete capitals in Europe, with a dedicated express train reaching the airport in well under twenty minutes. Coffeehouse culture runs deep here, an old, slow-paced ritual rather than a quick stop. Winters are cold, summers mild, and the city feels calmer and more formal than many of its European peers.

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.
