Sit on the Left side of the plane for the best views on flights from Budapest to London. The left side delivers the standout moment of the flight — a direct overhead view of central Budapest with the Danube, Parliament, and Buda Castle on departure. The landing views at Gatwick are pleasant but relatively modest green countryside on either side. The Budapest departure on the left is the clear highlight of the journey.

During takeoff from Ferihegy (BUD), sit on the Left side for the best views. Budapest Ferihegy's primary departure runway 31L/31R sends aircraft northwest over the city. The left side gives you a direct view over central Budapest — the Danube bend, the Chain Bridge, Buda Castle, and Parliament are all clearly visible as you climb out. The right side looks southeast toward the flat Hungarian plain with little of interest. Notable sights include: Danube River and its bridges through central Budapest, Buda Castle on Castle Hill, Hungarian Parliament Building on the Pest riverbank, Gellért Hill with the Citadella fortress.

When landing at Gatwick (LGW), sit on the Right side for the best views. Gatwick primarily uses runway 08R/26L oriented east-west. Arriving from the east on runway 26L, the aircraft approaches from the southeast over the Surrey/Sussex countryside. The right side gives views over the North Downs and the suburban sprawl south of London, while on clear days the London skyline including Canary Wharf and The Shard can be seen to the north on the right side during the base leg turn. Left side faces south toward open farmland. Notable sights include: North Downs ridge line in Surrey, Crawley town directly below on final approach, M23 motorway corridor, distant London skyline with Canary Wharf towers on the horizon to the north.

The flight from Ferihegy (BUD) to Gatwick (LGW) takes Approximately 2 hours 35 minutes.

The route tracks northwest from Budapest across western Hungary and Austria, passing near Vienna, then across southern Germany and Bavaria, over the Rhine Valley into France, crossing northern France near Reims and Paris, then the English Channel before descending into Gatwick. The Alps are visible to the south as a distant white wall during the Austrian and German segments. The Rhine and its valley are visible crossing from Germany into France. The English Channel crossing takes roughly 20 minutes.
