Sit on the Left side of the plane for the best views on flights from Vienna to Frankfurt. The left side wins overall because the Vienna departure offers genuinely spectacular urban and river scenery over the Danube and city center. During the cruise phase heading northwest, the left side also tracks closer to the Bohemian highlands and eventually the Bavarian landscape. The Frankfurt arrival on the right is good but brief, and the left side departure view from Vienna is the highlight of the flight.

During takeoff from Schwechat (VIE), sit on the Left side for the best views. VIE typically departs westbound on runway 29, so the left (south) side gives you a view back over Vienna's city center, the Danube, and the Wienerwald hills. The right side faces north toward flat agricultural plains with little of interest. Notable sights include: Vienna city center and Ringstrasse, Danube River bend, Wienerwald (Vienna Woods) forested hills, Neusiedler See lake to the southeast.

When landing at Frankfurt Main (FRA), sit on the Right side for the best views. FRA typically lands from the east on runway 25L/25R, meaning the aircraft approaches from the east heading west. The right (north) side gives a clear view of Frankfurt's skyline as you descend over the Main River valley. The left side faces south toward flat Rhine-Main plain with less visual interest. Notable sights include: Frankfurt am Main skyline (Bankenviertel skyscrapers), Main River, Taunus hills to the north, Rhine River visible in the far distance to the west.

The flight from Schwechat (VIE) to Frankfurt Main (FRA) takes Approximately 1 hour to 1 hour 15 minutes.

The route passes over the Czech Republic's South Bohemian region with its forested plateaus and fish pond landscapes, then crosses into Bavaria over Nuremberg and the Franconian highlands. The Danube is briefly visible again near Regensburg on the left side. The terrain is gently rolling throughout with no dramatic mountain crossings — this is a low-altitude central European corridor.
