Sit on the Left side of the plane for the best views on flights from Dubrovnik to London. Left side wins throughout: the Dalmatian coast and Adriatic islands on departure, then the Alps crossing over Austria and Switzerland where the left side looks south toward the main Alpine chain, and finally the Thames and London landmarks on approach. Right side has the Dinaric Alps on departure but loses out for the rest of the journey.

During takeoff from Dubrovnik (DBV), sit on the Left side for the best views. Dubrovnik's runway 12/30 means departures typically head northwest or southeast. On a northwest departure, the left side gives you the Old Town of Dubrovnik directly below, the Elaphiti Islands scattered across the Adriatic, and the Dalmatian coast stretching north. The right side faces inland toward the Dinaric Alps but loses the coastal drama quickly. Notable sights include: Dubrovnik Old Town and city walls, Elaphiti Islands (Šipan, Lopud, Koločep), Pelješac Peninsula, Adriatic coastline stretching toward Split.

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow typically lands on easterly runways (09L/09R) in prevailing westerly winds, with the approach over west London from the west. The left side on final approach from the west gives a clear view of the Thames snaking through central London, Windsor Castle, and the city skyline ahead. The right side faces north toward the M25 corridor and suburban Middlesex with less visual interest. Notable sights include: Windsor Castle and Windsor Great Park, Thames River bending through west London, central London skyline (Shard, Canary Wharf towers on the horizon), Wembley Stadium arch.

The flight from Dubrovnik (DBV) to Heathrow (LHR) takes Approximately 3 hours 10 minutes.

The flight tracks northwest over the Adriatic then crosses the Julian Alps and Austrian Alps near Innsbruck, passes over southern Germany and Bavaria, crosses into France near Strasbourg over the Rhine Valley, then tracks northwest over the Paris Basin and English Channel before descending into London. The Alps crossing over Austria is the most dramatic midpoint feature, with the Inn Valley and Bavarian foothills visible below.
