Sit on the Left side of the plane for the best views on flights from Karachi to London. The left side wins overall. After takeoff, you lose the city view quickly on either side, but during the cruise the left side tracks the Balochistan highlands, southern Iran, the Zagros Mountains, eastern Turkey, the Bosphorus region, the Balkans, and then delivers the superior London approach view. Right side sees more open desert and sea through Iran and the Gulf.

During takeoff from Jinnah International (KHI), sit on the Right side for the best views. Karachi's main departure runway 25L/R sends aircraft westward over the Arabian Sea before turning north. The right side gives you the city sprawl, Clifton Beach, and the harbour as you climb out. Left side gets open sea almost immediately. Notable sights include: Clifton Beach and Sea View promenade, Karachi Harbour and port cranes, Manora Island at the harbour mouth, the dense urban grid of Defence Housing Authority.

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow's dominant runway 27L/27R means aircraft approach from the east over central London. The left side on final approach gives you the Thames, central London landmarks, and the City skyline. Right side sees suburban west London and Windsor. Notable sights include: Thames River snaking through central London, The Shard and City of London cluster, Windsor Castle and Windsor Great Park to the southwest, Wembley Stadium arch.

The flight from Jinnah International (KHI) to Heathrow (LHR) takes Approximately 8 to 9 hours.

The route crosses the Balochistan plateau and the Makran coast region, then transits southern Iran and the Zagros Mountain folds visible as corrugated ridgelines, crosses eastern Turkey near Lake Van, passes over the Black Sea or northern Turkey depending on routing, then traverses Bulgaria and central Europe, crossing the Alps if routing goes slightly south, before descending over France and the English Channel into London.
