Sit on the Left side of the plane for the best views on flights from London to Gibraltar. While the right side wins at Heathrow departure, the left side dominates the majority of the flight. Tracking southwest over France and the Bay of Biscay, the left side picks up the Pyrenees as the aircraft crosses into Iberian airspace, views of the Spanish meseta, and then the spectacular Gibraltar approach. The left side's Gibraltar arrival view is the single most dramatic moment of the entire flight.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow departures heading southwest on runway 27L/27R give the right side a clear view over central London as the aircraft banks. You'll see the Thames snaking eastward through the city, with the urban sprawl of southwest London spread out below. Notable sights include: River Thames through central London, Windsor Castle and Windsor Great Park to the west, the M25 motorway ring, suburban southwest London.

When landing at Gibraltar (GIB), sit on the Left side for the best views. Gibraltar's runway 09/27 runs east-west along the narrow peninsula. Aircraft typically approach from the west over the Bay of Algeciras, meaning the left side gets the dramatic view of the Rock of Gibraltar rising sharply from the water, with the Spanish coastline and Algeciras visible across the bay. Notable sights include: The Rock of Gibraltar (425m limestone monolith), Bay of Algeciras, Algeciras city on the Spanish shore, the narrow Gibraltar isthmus connecting to Spain.

The flight from Heathrow (LHR) to Gibraltar (GIB) takes Approximately 2 hours 45 minutes to 3 hours.

The flight tracks southwest over the English Channel, crosses Brittany or the Bay of Biscay depending on routing, passes over northern Spain and the Pyrenees mountain range (visible as a significant east-west ridge), crosses the Spanish meseta plateau, and descends toward the Strait of Gibraltar. The Strait itself — where the Atlantic meets the Mediterranean — is visible on approach, with Morocco's Rif Mountains visible across the water on clear days.
