Sit on the Right side of the plane for the best views on flights from London to Warsaw. The right side wins overall because the London departure view is significantly more dramatic and landmark-rich than either side on landing at Warsaw. During the cruise, the right side also faces generally south, offering views over the North German Plain, and on clear days the Oder River valley as you cross into Poland.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow typically departs eastbound on runways 09L/09R, so a right-side seat faces south over central London during the climbing turn. You get a clear view of the Thames snaking through the city, with the dense urban grid of west and central London spread out below. Left side faces north toward the suburbs with far less to see. Notable sights include: River Thames through central London, Wembley Stadium (distinctive arch), Windsor Castle and Great Park to the southwest briefly visible before the turn, Canary Wharf towers on the eastern horizon.

When landing at Okecie (WAW), sit on the Left side for the best views. Warsaw Okecie typically lands from the west on runway 33, meaning the aircraft approaches from the south-southwest. A left-side seat faces south and east, giving a view over the Old Town and city centre of Warsaw as you descend. The right side faces away from the city toward open farmland. Notable sights include: Warsaw city centre and Old Town district, Vistula River cutting through the city, Palace of Culture and Science (tallest building, unmistakable), Warsaw's modern glass skyscraper cluster around the central station.

The flight from Heathrow (LHR) to Okecie (WAW) takes Approximately 2 hours 30 minutes.

The route crosses the southern North Sea near the Dutch coast, then tracks over the Netherlands and northern Germany across the flat North German Plain. The Rhine-Ruhr urban agglomeration is visible to the south. The route then crosses Brandenburg, passing south of Berlin before descending into Poland over the flat agricultural landscape of Mazovia toward Warsaw. No significant mountain ranges on this route — it is predominantly flat lowland geography throughout.
