Sit on the Left side of the plane for the best views on flights from Frankfurt to Porto Alegre. The left side wins overall because the Frankfurt departure offers the more dramatic and memorable urban and geographic views — the skyline, the Main River, and the Taunus ridge — which are genuinely distinctive. The landing views on the right are excellent for Lago Guaíba, but the left side also captures the lake on a slightly different angle during approach, making it competitive. The takeoff experience tips the balance.

During takeoff from Frankfurt Main (FRA), sit on the Left side for the best views. Frankfurt typically departs southwestward on runway 25C/25R, meaning the left side faces south toward the Taunus hills and the Rhine-Main plain. You get a clear view of Frankfurt's skyline receding behind you, with the Main River visible as a silver ribbon cutting through the city. Notable sights include: Frankfurt skyline (Bankenviertel towers), Main River bend, Taunus ridge to the north, Rhine valley in the distance.

When landing at Salgado Filho (POA), sit on the Right side for the best views. Porto Alegre's Salgado Filho airport sits on the eastern shore of Lago Guaíba, and aircraft typically approach from the east or northeast. The right side gives you the best view of Lago Guaíba's broad expanse and the city's waterfront peninsula as you descend. Notable sights include: Lago Guaíba waterfront, Porto Alegre city center peninsula, Guaíba River delta wetlands, Serra Gaúcha foothills to the northeast.

The flight from Frankfurt Main (FRA) to Salgado Filho (POA) takes Approximately 11 to 12 hours.
